approximately six years later than Pioneer's SX-1000TW first SS Receiver follows Sansui's first solid state model TR-707A with the output power devices 2SC2261 from Sanken and output/driver transformers.
Who can post the schematic?
Looks like Sansui used the same case as the previous tube 220 and tube 250 amplifiers!

the losses are the same resp. even larger;

====================================================
Trio Supreme 1 Stereo amplifier. Price: 298. Distributor: B. H. Morris & Co. (Radio) Ltd., 84-88 Nelson Street, London, El.
To the best of my knowledge the Trio Supreme 1 stereo amplifier is the only one on the British market which uses completely separate amplifiers for the bass, mid-range and high-frequencies although, whilst attending the recent Audio-Visual Equipment Exhibition in Paris, I heard Of other manufacturers who are proposing similar designs. Multi-channel amplifiers have been available previously and
I well remember the Sound Sales Tr-channel mono valve-operated system designed by the late Roy Wellington.
The Trio Supreme Is designed primarily for professional use for it requires modifications to the loudspeaker system in order to operate it correctly. Most loudspeakers consist of two or three drive units with built-in crossover filters. The filters in better equipment are complex and expensive ***, not only are they required to have a reasonably precise pass band, but they have to incorporate attenuators to match the acoustic outputs of the units.
The alternative approach as adopted by Trio is to use separate amplifiers to drive the bass, mid-range and tweeter speakers, six separate amplifiers for stereo. The following advantages accrue, It was each amplifier is directly connected to its own speaker unit, a high damping factor is maintained with a better transient response, (2) the amplifiers each cover a limited frequency range and this reduces intermodulation distortion. (3) it is difficult to design a cross-over filter using inductors and capacitors with a steep cut-off and (4) the individual volume controls for each channel enable one to balance the system for particular room acoustic conditions.
Thus, to use this amplifier correctly, one must either disconnect the built-in crossover networks on design an enclosure around three selected units. The amplifier is supplied with two colour coded. six-core cables terminated in wander plugs.
The Trio Supreme I amplifier is a most impressive design, beautifully engineered and finished in matt silver and brown, housed in a polished wood cabinet. The front panel carries the following controls: A row of six push-buttons selects the inputs, high and low level pickup, tape head, microphone tuner and auxiliary. Below is the mains on/off switch and tape monitor switch, to monitor a programme whilst recording. The mode rotary control has five positions: Mono, which parallels both channels, Reverse which switches, left enclosure to right and vice versa, Stereo. Left which provides mono reproduction only on the left loudspeaker, and Right which provides mono on the right speaker. The large volume control is mounted concentrically with the balance control. Four further rotary controls are for bass and treble of each channel and are calibrated in frequencies. Below these are four switches to control the fixed filters that operate at 40 and 80Hz, 2 and 5kHz, and 6 and 9 kHz, the central position in each case cancelling the effect of the variable controls.
Beneath a hinged lower panel are a switch to select the appropriate sensitivity for the phono 2 input, left and right microphone jack sockets, tape play and record jack sockets, phase reversal switch for the loudspeakers. six volume controls for bass, middle and high speakers for each channel, calibrated in decibels.
The back panel carries six pairs of terminals for the left and right loudspeakers. three 100W unswitched AC outlets, one 100W switched AC outlet. 2 Amp. fuse holder, fixed mains cable, separate earth terminal, DIN socket for tape play and record, six phono sockets for low level and six for high level inputs, two sockets for pie-amplifier output and two for recording output. Finally, two switches select bass cross-over at 400 or 800Hz and treble cross-over at 2,500 or 5,000 Hz.
Removal of the Outer cover reveals a finds conceived and constructed chassis carrying a total of twelve separate amplifier printed circuit panels, two power rectifier panels and a highly stabilised regulator panel. The input circuits, tone control and filter stages are fully screened to keep spurious signals out of the highly sensitive amplifier. The pie-amplifier stages plug into each separate power amplifier. the mid-frequency and treble amplifiers being secured to the main chassis which assists as a heat sink. The bass amplifiers handle greater power and so considerably larger heat sinks arc' used. With a total of 53 silicon transistors one might expect that only a skilled engineer could find his way round the circuit yet the layout is so logical and clearly marked that one call follow it in a very short time.
Every care has been taken to prevent earth loops and some quite massive earth conductors are used. The individual components are of very high quality and one would expect many years of trouble free operation. An interesting feature of each power amplifier is the automatic protection circuit which comes into operation immediately the circuit is overloaded. For example, if one applies a sine wave input to any circuit, observing the output across a dummy load with an oscilloscope, Specification and Test results: Trio Supreme I and gradually increases the input signal, the trace increases in amplitude then symmetrically starts clipping. Increasing the signal further suddenly causes the output to disappear and. after a few seconds, it re-appears. II the input signal is left at the overload level, the output switches on and off without causing any damage to the amplifier.
Performance tests
The accompanying graphs show: Fig. I the overall frequency ITSPOCISC and *** of the tone control circuits. Fig. 2 c-f-bet of the switched filters, and Fig. 3 the band pass characteristics of the individual amplifiers.
With such it complex amplifier. hearty hours were spent in measuring the various parameters and in general hey agreed wit Ii the maker .s specification.

Having assembled the amplifier and loudspeaker system it was tried with various input signals. including the unique Trio supreme 20 photo-electric cartridge (reviewed in the lance-amy 1969 issue). The success of the system must depend oil the choice of' the separate I ciii dspea ke-r units and I found it difficult. riot impressible-. under dome-stir conditions tee hear any real advantage ni having two lots of three amplifiers and separate speakers. against two a mph tier channels and welldesigned enclosures with built-in crossovers. Admittedly the Trio hits one use speaker drive units of difl3-ring sensitivities, and gives a unique d egret- of individual control. But most integrated three-way speakers are probably best fell alone.
Thcrefoic it would appear to me that trier should marker it special enclosure housing three individual uitiis ne the same way that Sound Sale-s did sonic- IS years ago. Considering that oiiu is investing ne:-arl L300 in the amplifier. its main appeal will bv to the professional riser. for cvheni it has a considerably ss'icln'r range of facilities and control than any other amplificion the British market.

Graetz Monaural Power Amplifier from 1963 Model "1262" with AD139 or AD148
This power amp was a special offer for the universal car-audio/home audio/traveller mono reveiver "Super Page". Receiver and mono amplifier very hard to find.
From an other guy I have heard, that the sound was not loud, but very clear and tight both in the car and at home. Unfortunately he sell it for approximately 25 years

Very first HiFi Solid State? Transis-Tronics (Transistronics, TEC) FM-15/S-15, 1962
TEC (Transistronics, Transis-Tronics, a corporation of California)
TEC FM-15/S-15 (FM stereo tuner/integrated OTL amp)
some sources write, that this model was the very first solid state amplifier for home audio. Pics are very hard to find. After find out the right exactly company name, I have find nevertheless a lot of Informations:

http://www.aes.org/aeshc/docs/vonreck_electronic-home-music.pdf
The first transistor high-fidelity amplifiers
were produced in 1961 by Transistronics [66], the model
TEC S15. A matching tuner, model TEC 15 MPx, was also
offered. In the following years a number of companies
offered transistorized music reproduction equipment.

more TEC Types: Transistronics TEC-25 transistorized stereo amplifier
(also Widlar's 709 from Fairchild was mentioned,
OP-Amp first comercial use by Scott 1969)
About TEC's Solid State amp from 1961 model No "V-16" V16 no information to find (mentioned in an old german electronic magazine, perhaps thw wrong model No).
The same situation I note by the TEC "S-25" (S25)
