Tube Amp Archive

Yes I can switch with toggle into OD. Relay work fine they switched, footswitch work fine, PAB relay work fine. Diodes on relay bord are correct.

I add some photos.

I will add a photo today. Yes I have toggle switch on panel to switch OD manually. It work ok. I check relay as I mentioned. It's ok to.

Ha Ha!!!

Sorry I lived in Poland. We don't have qualified technician.

HI!!!

Today I removed relay from the amp. I connected OD stage straight ahead. And I tell You THIS IS NOT RELAY PROBLEM. I check the wiring inside the amp and solder points. And it still not work. Plate voltage on tube is ok.

No when I touch the V2 plate resistors I don't get a pop through the speaker.

Yes I play with the tubes and nothing changes.

Thanks!!!

I check the relay soon as I can. I used a brand new Finder relay. And if it's not relay?
Do you have any ideas?

Hi!!! A few time ago I build my Dumble style amp. It work great!!! Clean and Drive sounds delicious!!!! And now suddendly the drive stage didn't work. I don't now why. 3 monts works ok. I play it yesterday. Today I plug it and i can't hear any signal from guitar only humming like "FM radio tunning"....

What do you think about this solution to conect reverb in that way?

Hi!!!

Thanks for a help!!!

So I redrawn the schematic and improved the values that You suggested.

Now it's correct?

Hi!!!

Does anybody built a one tube reverb? I have a schematic but i don't know that component values are all correct. It sounds good? Sorry for my english.
