I will be reverse-engineering it this weekend and work on it's shortcomings. Again, there are characters very similar to the original amp, but again a little too bright and fizzy and missing a MIDdle control. I also recently purchased a Friedman BE-OD.
#MARSHALL JCM800 SCHEMATIC ROB MODS#
There has been some suggested MODs over the years. Here’s the schematic with the points labelled 1 to 17: And here’s the voltage data associated with those test points as found in the service.
#MARSHALL JCM800 SCHEMATIC ROB PDF#
I found a PDF of the old Marshall JCM 800 Service Manual which included some example voltages at various test points in the preamp circuit. I'd like to then add some switches to change a few things such as Jose Arredondo MODs, maybe a 3-position on the NFB as well as 3-way on the presence cap value and possibly add a Depth/Resonance MOD, but first to get the baseline. Marshall JCM 800 Service Manual and the Modulus layout. I'd like to also include a 9V/18V LO/HI switch on it. Its the ultimate 100-watt plexi-style amplifier with maximum flexibility, maximum functionality and zero compromise in components, signal purity, and tone. Then, change the values to more represent the 2203/2204 circuit and see if better or not. The Metropoulos DVL-1 (William DuVall Signature) William DuVall of Alice In Chains and George Metropoulos have paired up to create the greatest Metropoulos amp yet, the DVL-1. I would like to build this up again and see how it is. The original circuit only has gain and volume and I don't want to fight volumes thru the circuit. I have referenced Rob Robinette's awesome website which has a layout that I used (minus the elevated heaters) and discussion on the. Tranny's are pro/super reverb type spec, and im running 6l6's, but having numerous fender type amps I opted for a JCM800 as an experiment. I didn't care for the gain, volume, then master volume. Just finished up a home build with mostly re-used parts. CeriaTone has classic circuits to offer, as well as custom made to clients specifications. We at CeriaTone would be happy to serve your needs, whether you are a DIYer, an amp shop, or a boutique amp manufacturer. Built on a two-channel design with clean and overdriven channels, this monolith amplifier incorporates industry standards like a three-band EQ on the. Thank you for visiting CeriaTone, home of quality and affordable guitar tube amplifier. Looking over an actual 2203/2204 and in the Phase Inverter circuit. The Marshall JCM 800 2205 50 Watt Head is a legend in the companys roster, informing the Marshall tone since its introduction nearly 30 years ago.

This design I built up and had a LOT of positive things about it. I just wanted to circle back around to this pedal and design.
