Anyone got a Bandido umax 2 ?

Just a question to help me really. In the ALL METAL mode do you find that you can alter the DISC and get a 'reaction' from the spkr/phones, but this does not actually affect the ALL METAL operation ?
This is what I find with my clone and I don't want to hunt a problem that isn't there, especially as everything works so well now. If you are a techie, then I think the effect is caused by a small variation in the sine wave due to the way the DISC op amp is configured - I think it cause a slight 'wobble' in the GROUND BALANCE circuit.
Many thanks.

Most probably the power consumption is altered by a wincy bit and it affects all metal somehow. Beefing up the electrolytic capacitors, or replacing them with low ESR should do the trick.
