Nice. I prefer them in my system too. Show us your new build when ready.

May i ask, in DCG3 can i use the psu of yarra preamp ?

You can use any +/- 17V +/-300mA capable PSU you trust and like.

Fellow member filenet did just that and he's happy with the results

Salas, working on second preamp build, would 1.74k be alright for gain resistor ? To get 4x plus ? 3 x feeding burning amp Wide open is normal listening level. Need just a little more. Also what is the lowest resistance you would go to get close to unity gain when driving an F5. Try around 400 ohms? Thanks Mark

1.74k will give ~4.5x gain. It won't oscillate with more than usual gain setting, its ok.

499R would be the lowest. 2x gain. Further down its dangerous to act up. I don't guarantee it will stay stable. Unity it does not do for sure. You could try push it to 1.5x but you should fully check on the bench it still works calmly with gen & scope on sine and square.


P.S.

The gain formula is 1+(R6/R7)

Salas how you didnt desing a power amp so we are going to have a SALAS complete system?

A question I have been wanting to ask!

There was a KT88 trioded tube amp I had actually designed :D

Many speakers also. Including professional installation types

Anyways, for electronics I generally designed what I missed or to put interesting or expensive lying around parts in use. Power amp solid state designs are so proliferate and accessible that I always had something satisfying on the rack. But I may try my hand on one sometime too just for grins

Well then i think that we all are waiting for your ss amp!!!


Thumbs up
