I think so, probably in a week to 10 days. The first 5 went almost instantly, the second batch took a couple of weeks to disappear. I think I'll try 5 more and see how it goes.

Lots of $$ tied up in parts if I sit on them too long

Hi Pete,
Need your help. Was measuring valve THDs with great entusiasm and found that some last measures on the 26 triode was a bit high when I realised that the interface wasn't working properly. Feeding it with a 1Vrms I get a very low signal into the soundcard and is distorted. When I tried to GND then the LCD meter goes blank and need to keep it in FLOAT.
I realised that I applied more than the 10VACrms expected as I was testing THD on the valves at about 20Vrms.

It looks like I screwed up the interface input, is that the case?
Any help is appreciated!!!
cheers,
Ale

Ale -

Well, sounds like something is broken... the input is pretty well protected, (certainly 20V RMS should not kill it) so I'm not sure what may have broke. The meter going blank when you activate the GND switch is curious - I really do not understand how that can happen! Does this happen even with nothing connected to the input? Does that still happen if the input is set to "GEN MON"?

Did you have a large DC bias on the inputs?

Pete
