Build quality is poor, and it is tubes down and built like a Fender head. It is original. I have been asked about this amp many times. It is a JCM 800. You can see the Hammond PT. The OT is Heybour, their  Drake copy these 2. Reasons. One is it has a package rectifier and 10000uf cap to make DC filiment see for preAmp and PI tube.


Needs a service and about 30 feet of leads cut. The guild quality is poor and against my clone, which is tubes up, my clone is simply built better. Look close at the solder joints. Yep, removing.rhe board to clean it first.


Nice sounding amp. Went silent when the filiment package diode failed. Get this, 3 amp diode. Would get hot. His failed and I will replace it with a 10 amp version since I have on hand.
It matches the Marshall schematic exactly, Even the 5.6k cold clipper. Mine switches.2 more values.
I planned to post this the next time it needed tubes. Great sounding amp. Very manageable volume of you use JJ6v6s.

A Fargen ole 800. Runs El34 and the tonestack is nice. The OT is 3.3k/4,8,16
Very nice cleans. Putting a loop, but only after I rework the 2 blue wires. Too long and break where the resistor is soldered to the socket. It rocks.

Are there schematics for this around?

cool stuff ed! what value are the TS pots and mica treble cap?  i see 22nF caps for the mid and bass controls and 33K slope resistor. agree build quality is not all great - some of solder joints are borderline gray and a couple have voids.

some of those leads do seem excessive in length. the B+ diode tap to the standby switch is a joke and should be corrected.

thanks for sharing, ed.

Ed would it be possible to see a picture of the faceplate please?  Thanks.

Sorry guys, I will get the info you asked.  Life is no the way right now.  I traced a 2204 Schematic and other than the inputs.  Couple of partial Faceplates.


This this is a just a 2204 with DC filaments.  I have had to patch this amp for a friend many times now.  He took mine to use until I get a chance to rebuild this one.  I cannot remember any difference, but that STBY Diode setup was omitted on my build.  I stuck closer to the proven Marshall design.


Just thought I would share the amp.  Every once in a while someone just gets an amp that sounds really good clean and overdriven and this one is one of those, However the bastard did eat a pair of my Mullard XF2's.  I cried! :cry:


I will follow up as time allows.
