Let’s talk about mid-‘70’s 50 watt Marshalls: 4 inputs (non master volume) with Printed Circuit Boards

[topekatj]

Been a Fender guy since I began playing but have gotten a weird ITCH recently to buy a 50 W Marshall! Don’t have crazy money for a ‘73 or earlier PTP amp. How do the PCB 4 holer’s stack up? Also, short of some hack job master volume mod, what’s the best current technology to dettenuate the volume for household use? I’m aware of the Weber MASS units — is there something superior?

Thanks

I also learned recently that Marshall built the some of the 1st gen MV heads in the old/original looking (plexi style) head cabinets. Obviously they're not four input units. 

There was a 76 or 77 4 holer JMP with original factory master volume posted in the Marshall Facebook group just last week. Rare as hens teeth, but they made a few.
