Okay, I have finally had a moment to sit and take real look at what is going on inside this amp. Yes, the AC was cut to the bulgin plug. However, it looks like the ground wire from the new cord was tied to the ground in the bundle coming from the bulgin. As I see it, unless that grounds somewhere I...

Sure, happy to post what ever you need although it will possibly be a few weeks before we get started on the restoration. I'll definitely be around with a question or two because biasing this thing will be scarey. :shock: Have fun! Emil Thanks, if you need any help with biasing, we are here for you...

Oh yes, one more thing.

Could you please measure voltages on V5? That's the preamp tube in the middle.

That would be very helpful for my build, thank you!

About your bad luck with JJ-s

I also am curious about the EHX 6CA7? I gotta tell ya, I wasn't EH's biggest fan. Ran into some really nasty sounding 12AX7's that coloured my opinion. Recently, I've run EH 6L6's and 5881's in a couple of "F" amps and they really do sound good. Given the bad run of luck I've had with JJ'...

Probably like this: (add a slave out with two resistors)

Very nice! Also, if were you, i would replace electrolytics ASAP.

And how come IEC mains plug is female? It should be male for safety.

R.I.P.

There was one on ebay recently...

Very cool amp... I wonder if any former employees ever look here and if they would know anything about this one? You should definitely push to give it a recap so we can get to see some of those 'ominous' (D)R401 gut shots :mrgreen: +1 :D If you don't do recap, many bad things could happen... And I ...

Tell him that you need to check bias, as it gets changed by the time.
