Hello.
I've been gone from diyaudio a few years due to a few family crisis, but I'm back again.
I haven't been doing any DIY for a long time but picked up a old project, the famous p3a by rod,
I found a cheap chassis in used condition that fitted okay.
Its fully dual mono, will use crc supply.
In a few days it will be operational, and I'm quite excited about its sound.
I made the bias adjustment external, accessable on top of chassis, two 20 turn trimpots and four banana plugs, will make adjustment easy and precise I hope.

He is a charming boy, but I have to be very careful with solder wire , cables ,components, everything gets chewed on, hope is gets better with age, he's on 7 month old
Dc resistance is 0,34 ohm Each winding
80mH its a lundahl LL2772 in common mode connected on - and + rail
First had 75000 uF then choke, after that 31000 + 31000 per rail per channel. Bass was boomy and treble with sibilance. Replaced choke for 0,33 ohm and sound is much better
