Tube Amp Archive

Could someone please help... I have a jtm45 head that i run into a Jtm50 combo...plugging into the speaker... is it possible to have the speaker plugged into the jtm50 and the jtm45 selecting the source only by which is amp powered up?... So meaning both will be connected by a Y type plug to the spe...

Thanks rootz

Yes thats what I was hoping would the parts you mentioned match the parts i have so the tubes are el34 ss rectifier not worried about face plates it has ppimv... Is actually a really good build but i already have a jtm45 ceriatone the donar is a modulus 67 jtm50

Wild question but just wondering would it be possible to transform a Jtm50 black flag clone to a ods... possible?

With thanks to all who contributed special thanks to PDF64 who pointed me to the area that needed investigating i found the problem all goood

Yes el34

I wonder if this dry connection has something to do with it?

With the hum shows 36 then when it clicks and the hum goes off it shows 28

Ok the one on the left in the pic shows 33 the one on the right shows 28 with the hum but while i have the probes on the right one after a few seconds it low clicks and the hum goes off

Thanks PDF64 will do....
Would i red probe to 8 and black to chassis to get bias value just for future reference
many thanks

PDF64 could you mark where i need to take red and black mv from please im a noob but understand the dangers i will use a fluke177 with mv thanks in advance

Will have to check after not home atm

Not intermittent it will stay not go away
It seems to match the layout.
