I did not get my shipment of J113 so I used what I had on hand. BF245 selected for IDSS of 5 ma. I used 1 ohm resistors for R1 and R2. The pinout is different but no big deal. Works just fine

Hooked it up and woha , bass , lots of bass. My subs go down to 20hz so the difference between my capacitor coupled B1 buffer and the DCG3 is quite pronounced. Good imaging, dual mono power supply , looking good. I will need to do some more listening.

Nice first impression :up:

What type Q1 Q2 mirror transistors in your DCG3? BC560 or BC327?

Eslheadphone 19th March 2020 06:47 PM

Tea Bag supplies BC560C

They are nice too, maybe more sparkly than finer & deeper, but they could be lending better to counterpointing some subs. Anyways, it will need to play little few hours for the Pana FCs to fully come up from storage life.

Eslheaphone, I would put some insulation on exposed mains cabling for safety reasons.

I have had some time to listen to this preamp and I must say, I think it will be around for a long time. The sound just flows effortlessly, the sound stage is excellent . I hear more of the room , percussion is clean . I am driving 20 feet of Beldin coax with no problem. Now I need to build a nice phono preamp.
My thanks to Salas for a great design and to Teabag for those hard to get parts

You are welcome. Enjoy :up:
