bullpeters,at least the information on the Tetra is a step forward but there remains the question of how you utilize the stage gains to work with the Leak Stereo 20's high sensitivity of 125mV for 10 w o/p..Where is the volume control placed in the system and how do you switch from one item to the other?

One more point,a previous post said 12AX7 valves were fitted to the phono pre-amp and I notice in the cct description there is an alternative given with frame grid double triodes,the 6DJ8.I presume the constructors manual indicates the correct values for the resistors for the chosen valves as they are dissimilar.

Yes. They were the correct values and an EE friend had checked the RIAA for me.
There is a volume control (potentiometer) between the pre amp and the amp. The inputs are switched by a relay then thru the pot to the amp.

People assume that a mediocre analogue front end will sound amazing but that simply isn't the case. Analogue is tweaky and hard and always takes more effort that expected. At some stage i was stuck with a single turntable/arm/cart combo and the even though all the components were well regarded, they had no synergy and the sound was really unlistenable. These days i will not approach a new TT without a drawer full of cartridges and at least a couple of arms to play with. As for the riaa pre - it's more that capable of ruining the sound on its own.

I'm happy about the 'lick effect' !


Analog, have you seen my system ?
Assuming that <radio> is an analog source with perfect behavior...
Well, it works quite well !
Probably the volume/input/presetEQ IC and the very short distances
between the sections, supply to the evident lacks of those components themselves ....( which lacks/issues )

Have you ever think of having a one piece with no junctions ( that woukd be valid also for the cartridge pins, electrically speaking...) instead of the ISO
shells holder ?

beat me to it! yes the Tuner is Analogue. My wife is Asian and she says burning certain herbs makes the whole system sound better. she thought licking the pins was BS!
She worked in FM radio and knows more about turntables etc than I ever will

Smoking certain herbs will make it sound better, too.

Not sure if i get your meaning right but if you mean not using headshells, then yes, none of my arms use headshells and at least one is rewired with a single piece of wire between cart clips and phono pre. Not sure why this would matter.

No, i haven't seen your system but at some stage have owned your Leak setup inclusive of the tuner (no stereo decoder though) and have a pretty good idea how those pieces sound.

While i have kept great memories from the sound of several tuners i still maintain that the sound coming from them, although pleasant is very heavily processed - it's in the nature of FM distribution.
