Hi HH,

You have the transformer section in a separate chassis as I can see, very nicely done!

All the best!

I built the USSA-1 and the USSA-5 and these amplifiers are an acoustic treat, so it is logical that I will embark on the construction of the USSA-3 following the encouraging comments.

Hey Do,

Yes, I am running my transformer section in a separate chassis with chokes (CLC). It is a heavy solution that takes up a lot of space, but that way I can use the transformer section on several amplifiers.

You definitely should build the USSA-3. You will not be disappointed

Default repair and improvement of an older project

Iíve been repairing and improving previous builds lately. Nothing seems to work great the first time.
This is several improvements to a preamplifier I built about a year ago, post # 5082. Changes include.
The original build had the PCB from the NAD P100 phono preamp. It had some bad connections, so I replaced it with and Elliott Sounds Product phono preamp (P06) http://sound.whsites.net/project06.htm and a subsonic filter (P99) http://sound.whsites.net/project99.htm
I damaged the power supply with a careless wiring mistake. So I rebuilt it, and added 0.4A fuses.
Overall I rearranged things to make the wiring more neat and tidy.

1. Subbu DAC V3.0
2. Subbu DAC power supply
3. Twisted Pear USB DAC
4. Elliot Sounds Product power supply, P05B
5. Elliot Sounds Product preamplifier, P37
6. Elliot Sounds Product phono preamp, P06
7. Elliot Sounds Product subsonic filter, P99
8. Ground loop interruption circuit
9. Gold Point selector switch
10 Gold Point volume control.
