Hi. I bought a used MA50C as my first ever Marshall. I was taken by the clean. and the blend knob clean crunch was also a big plus. now you can have crunch with a clean bottom. Nice. So I got it used. And there are some issues. Wich the owner was very upfront with and the price was accordingly. So i'm okey with it. I turned up the amp an ticked the powertubes. They are microphonic. I got the amp with the spring reverb separated. The leads in the tank were resoldered but when I put the reverb back no sound. If the reverb rattles it can be heard in the speaker tho.
Since the solderingjob was fairly ok my first impression is it might be a fuse. Is there a fuse in the MA50C guarding the reverb signal? The amp works well. When I took out the chassis. I saw that all caps are ok and nothing is damaged on the circuitboards. The amp was used half a year. Before that it had been in a store.
The amp is 63,5 cm wide. And Marshall does not carry a 1x12 cabinet that wide. Wich is too bad. Cause I'd love to have a cabinet underneath this amp. The Eminence AX75 sounds quite honky. I have two 1x12 Trace Elliot cabs wich have Celestion 80 lead speakers in them. Would I use those or order a 25 watt 16 ohm greenback?
