I change all the tubes, with no result.
The sound with no guitar plugged remains, and still is very loud.



PS: 100pts, a lot of time...

Have you tried manipulating the components around with a chopstick, looking for cold solder joints and damaged resistors and capacitors ect?
Stew
PS. Phil/Coco what would the effect of a leaky cap be in the coupling/tone area be?

Yes, I find nothing strange.

To reverse the OT leads (Blue / Brown) at the tubes, Can be a solution?.

No that wont solve a hiss problem. If moving a tube makes no difference, & the noise is there with no guitar plugged in, it wouldbe worth reheating all your solders joints in that channel only. and adding a touch of solder . Check for good grounding ( < 1 ohm ) as well.

The rectifier valve may be the cause? is the only one I have not changed.

The rectifier valve affects both channels. The same with the power valves and the phase invertor. So if anything was wrong with those, it would affect both channels equally.

You are saying that the noise is only in the Normal channel. So the problem can only lie in a small part of the amplifier.

Did you change V1 with a completely new and different valve, or did you just swap the valves around that were aloready in the amplifier?


Voltages would look wrong and/or the controls wouldn't opperate correctly.

At last!! . I reflux all the grounds, seems to have been a bad solder joint.

But the normal channel seem to be more noisy for me than the TMB. Is normal?. I think I'll investigate more about this channel.

The sound of the amp it's incredible, and the TMB channel it's pure tone.

Thanks a lot to all who have helped me. You are great.

Regards.

I'd think the TMB channel would be noisier due to it's gain but it sounds like you are on your way.

Hello everybody, after have spent a few weeks testing, and the amp sounds great. But today I have a problem. . I turned on the amp and when I flip the standby I get a hum coming from the speaker , but no sound from either channel.
I looked at the valves and look right. Any idea where to start to debug?

Thank you

Problem solved!!. It was an unsoldered ground, reflux and all it's OK.

Regards.
