Tremolo 50w service
Servicing a Marshall Tremolo 50w pretty much original a few things have been worked on. Power cord is completely crumbling in my hands. One wire on standby switch is undone. Pilot light broke.
Fun amp for me to bring back to life.

i'm a killer. that one looks pretty good!
hmmmmm shared, drilled board.. 10333... .1u.. pancake mix bypass.. 1968.
It is even a BB. Which cabinet did it come in? Does it have a valance or just cloth front?

Small box head with valance.
Re: Tremolo 50w service
Full iskra resistors inside ! Ex Yugoslavia, we were producing everything. Now it is only part of history. Looks like PI resistor 470R has been replaced for CC

Re: Tremolo 50w service
the 50w tremolos used the bass circuit, while theh 100w tremolos (supertremolos) used the lead circuit. So .1uf does not indicate 1968Reeltarded wrote: ↑Fri Dec 09, 2022 4:05 pm oh it wants me to strip it and make it scream!! look at it flirting at me with that 7 inches from sensible 4th noval.

Re: Tremolo 50w service
Ahh I mean the pres and I meant Mustard .1. Earlier amp is different and later amps end up with mixed brand caps. I used the serial range to predict production above my JTM50. Look at the bias trimmer. I think it's mid 68 and lost it's head hutch.
It has a combo lip. Somewhere, there is a sad lonely and expensive cabinet remnant under a bunch of rotting food waste and ink stained Barbie heads.

Re: Tremolo 50w service
Would you mind measuring the resistance of the HT winding? ie from the PT winding lug with anode of one rectifier diode to the anode of the diode on the other lug.
TIA.

Sure I can measure.
It has a beat up 4x12 cab.

Re: Tremolo 50w service
wow I LOVE THAT
It appears to have combo mounting holes for the front lip. I have only ever seen two heads done that way but maybe 10 heads with the lip.
