Tube Amp Archive

First off thanks Firestorm! Second. Is the cathode resistor and the cathode bypass cap on the 6V6 the ones circled in the schematic pic below labeled #1? If so do I need to test them in the circuit with power applied (tubes in or out?) reading voltages from the voltage chart in the schematic, or do ...

OK thanks I got it... I see which one it is. I'll look at the transformer to verify hot side. So When I replace the cord I can discard the dead cap altogether then correct? I know to make sure its discharged first. Vocational Heat and air guys in high school used to play bad tricks with start capaci...

Also I found a good data sheet for the 6V6 tube here with pinouts.

Ok I have done some reading and have some questions... First, on the dead cap. Is it the one in the schematic pic below labeled #2? And do I just take it out completely and put a three wire cord in with the green ground wire to chassis? Does it make a difference which side of transformer the hot and...

^^^^^ Great thread...thanks for the link M Fowler! You need a type 6X4 rectifier excellent military 6X4W type at $15.00 each. The 6V6GT is an RCA clear glass types at $40.00 each. ECC83 is also known as a 12AX7. The one in the picture is an Amperex Bugleboy from Holland. These are very rare, as they...

Thanks Firestorm! edit: BTW I have already read the thread in the link you posted. Thanks for the input on schematic. I've actually got a degree in Industrial Electronics but fell into the computer field after college so never really used a lot of what I learned in school. I am proficient at solderi...

Thanks for the info Chris. I've not been into electronics for quite a while now. Looks like I need to do some catching up. If I remember electrolytic is type of capacitor...which one is the death cap you speak to and when you say cut it out you mean it is ok to remove it and not replace it? Someone ...

Hello to all, This is my first post (Sorry for it being a long read!) as I recently registered here after looking around a bit. Apparently I have a somewhat rare old DeArmond R5 amp and am looking to find out more about it. Particularly what year it was made? What is it's value? What tubes did it co...
