I think the Naylors are still very handwired, but I've yet to find any decent schematics of their products.Īnd then there are amps that use voltage reducing circuitry to reduce volumes but keep the whole amp in its sweet spot. I also heard, on paper, great comments about Naylor amps and their master volume circuits. You can upload the JCM800 6V6 Hoffman circuit board DIYLC file to. Even if I had their schematics, it would probably be way over my head to implement it. The Marshall 2104 Master Volume/JCM800 is my favorite high gain amp of all time. I don't recall any of these owners stating a need for an attenuator.
MARSHALL JCM800 SCHEMATIC ROB FULL
Most owners of Mesa Boogie amps rave about how effective and musical their amps master volume circuits perform. I build this amp after RobRobs schematics of his Nakid SLO 6v6 This is just a test drive of the amp I got two minutes to blast it all at full tilt as they we. Marshall Amp Schematics to assist you with your amplifier repairs and modifications. But if I really need to " feel" my 50 watt monsters in my 120 square foot mancave, then my attenuator comes back into play. Or in the example with my two JCM800's, they have both: the stock pre PIMV and the post PIMV. Attenuators are all about getting into the amp's sweet spot, therefore running the amp hard and sacrificing some tube life because of it.Ī pre phase inverter MV might work better than a post PIMV on some amp circuits, while a post PIMV might work better on others. CeriaTone has classic circuits to offer, as well as custom made to clients specifications. From what I can make out on the schematic it is a fixed presence with a resistor. Also, there is no presence Pot on this model. We at CeriaTone would be happy to serve your needs, whether you are a DIYer, an amp shop, or a boutique amp manufacturer. Has anyone out there with the Marshall 4210/2205 split channels had any issues with bleedover between the two channels My version is a 1983 JCM800 4210 50 watt 1x12 combo with the 6550's. The 1959 (Marshalls identifying numbers are not years of manufacture), produced from 1965 to 1981 (when it was replaced by the JCM800), is an amplifier in Marshalls Standard series. But of course, an attenuator is very useful for any tube amp regardless whether it has a master volume or not. Thank you for visiting CeriaTone, home of quality and affordable guitar tube amplifier.
