    Yeah, speakers kinda suck but the cabinet is ok.

    1966a with G12M- 70s

    Yes, I agree. We aren’t gonna use it, 75s would have been good. Any date guesses in the cab?

    1966a with G12M- 70s

    So we picked up this cab over the weekend and it has a 4ohm G12M-70, the other speaker was an eminence, don’t really care about that one. The date code puts it October 1987, was Celestion still making these in 1987? I thought they were not very well liked. Just wanting to date the cab which...

    Ceriatone Plexi 50 build

    Kits to me are the way to go, bigger transformers, more robust parts and the ease of modding. Nik has a lot to choose from, surely there are models there for your tastes. Cheers

    Ceriatone Plexi 50 build

    Niks kits are very good and they sound awesome as well, that’s about all we build, easily available and his shipping for the kits is stupid fast. There aren’t any instructions other than the layout. The layout is good and I haven’t had any issues with them. They are correct and complete, some...

    Incoming! HNAKD, Mojotone MV JMP 2204

    Very nice build, I too would encourage others to get the kit, all the parts were very good quality. Mine is quite as a mouse as well. Here is mine.

    Incoming! HNAKD, Mojotone MV JMP 2204

    I’m with you on the blue board highlighting the yellow caps and also the white cans are kinda ugly. I did something new with this build, the heater wire on pin 9 I made it come up from the socket vs following the chassis to the corner. It’s a hybrid of Marshall and fender.

    Looking very nice, straight leads and nice wire dress. I love the attention to detail. The one thing I didn’t like was the blue turret board, yuck, I made my own. Your build looks great.

    Ceriatone Plexi 50 build

    Here it is, I wanted to get him to do the thread but he wasn’t too interested in that. Sounds very much like his Ceriatone Plexi 51. The purpose of this amp was to build and mod, he has been wanting to mod the amps but I won’t let him mod the ones I built so I bought this one for him. He has...

    Ceriatone Plexi 50 build

    The meter on the top is for output volts. I have 2 ways I can measure current. My old school Weston 433, or my Fluke. Believe it or not the Weston is just as accurate as the Fluke. And the meter on the Variac is a factory option. They rarely come up on eBay, I have 2.

    Marshall 9001 missing -15v for OP amps

    Hi Jon, thanks for responding. I lifted one leg on c46 and it measured its value, I didn’t check c35, but I do have a “Blue ESR tester “ and it measured good, I can remove it and check it though. Hiw do you lift one leg on a IC that has 8 legs?
