I would say 100VA would be minimum, and I normally use 300VA toroids. As to the voltage, 15-25V AC (dual secondaries or centertapped)

I thought it may be a good idea to post a link here to a place in Poland that produces affordable and very good transformers: http://www.toroidy.pl/index.php?page...emart&Itemid=2

Ask for a special audio version:

TS300VA PRI:115V SEC:2x22V for AUDIO:
- secondary at the core with 50% higher diameter, single wire (1,8mm)


I used such transformer in my best amp yet: http://www.diyaudio.com/forums/showt...609&highlight= althought it was amorphous core, which I hear is not available any longer.

The values should be according to schematic here: http://www.diyaudio.com/forums/attac...amp=1210693738

I have checked this and it was not the problem. I'm a bit stuck now. I'm considering making up the stereo config as in your pictures. If that works, then I will work backwards (or just leave it as it is...) The ony non standard bit of kit is the LED and RLED which I salvaged from a PC. Can this be jumpered or left out to eliminate it?

Thanks

Matt

Hi Peter

do you think that Toroidy transformers build for audio are better than Plitron of such type

If they were with amorphous core, they would be better, otherwise, they are certainly comparable.

BTW, I also used those tranformers in my Zv9: http://www.diyaudio.com/forums/showt...590&highlight=

Default Subwoofer on my 3875 amp

I just finished a chipamp.com LM3875. Thanks for the coaching and guidance Peter. I'm running a pair of FR Tangband speakers (3CR-Ti on the PE speaker projects page). I'd like to add a sub to get a little more bass. What is the best way to connect the sub to my amp? Is running the sub in parallel with my speakers, off the speaker jacks, the right way?
Thanks.
Mike

Off the speaker jacks for a sub will work.
