I finished my build yesterday and one of the large capacitors emitted lots of grey smoke, any suggestions on easy to source decent capacitors to replace all 4 with? I'm in the UK if that helps.

I'm using a 24v + 24v/400va toroidal transformer, when I tested to psu it gave 27.5v output. Is this too high?

I borrowed a Variac and didn't think to test the output of it for different dial positions, will do this before connecting again.

I have a 2x16v 300va C-Core transformer and my speakers are 8ohm. I read that the "ideal" voltage is about 22v. What would be the implications of using a 16v transformer? Just less power or are there also audible/sonic differences?
Many thanks!

With 16V transformer you will get less power as per attached graph (after rectification it will be approx 23V DC)
Also, the amp will lower rails will sound less dynamic and more mellow.

After the period of absence, the website is up and running again: Audiosector

The manual can be downloaded here: Manual

I also put all my major projects in one place: Projects – Audiosector

Presently, only LM3875 kit (Classic and Premium version) is available, this section of a website is still under construction but you can order it directly through me.
