You can set gain with different value of feedback resistors, 6-10dB is usual value.

HI every one !
how about SR800 ? if not, how about adding more Pairs of 2SC5200/ 2SA194 on SR250 or SR200. For example 5 Pairs of 5200/1943. Will it work well without changing anything ?

SR60
Any advise needed.
The SR60 (Olaf's) boards are filled with parts.
By viewing to 1837- hfe250-260 and 4793- hfe 220-230wish i have on hand, i feel they're not good matched, or could it work?
Is it necessary to have hfe more closed for better result- offset....?

Many Thanks Mile.
Than i heat up my solder iron and if all worked some impressions later.

in circuit below which one caps are effective for filtrate voltage?
i have 40000uf but I don't know where puts

Both "1" and "2" are filters.
Place the bigger ones in position "2", but do not remove caps from position "1" (you may use lower value ones, though).
Dear Apex Sir,
I am keen to make SR 200 Amplifier. Please advise whether to go with 4 pair BJT or 3 Pair for my PSU setup. Let me know if I need to change in PSU for this Transformer..
Toroidal - 55-0-55 , 1500 VA, 10 Amps
Capacitor - 60,000 uf / 100 v per channel. ( Total - 1,20,000 uf/ 100 volts)
Speakers - 10 inch Woofer - 8 ohms , 6.5 inch Kevlar Mid ( 8 Ohms) and Silk Dome ( 8 ohms)
Please guide me with suitable PCB link of SR 200 and PSU PCB link.
With Regards,
Samrat

As someone who has worked in the broadcast and mastering industry for 35 years:
Studio quality/standard = what ever the studio decided to buy, nothing more!
Most of what I have seen is Crown and Bryston. But there are countless other brands in use.
QSC seems to be the commercial and color mastering theater amps of choice these days.,
P.S. Nothing against the Apex design. Looks good to me.
