I have worked fine on JCM 800's and 1959's etc.marshall owners manual amplifier jcm800. Every now and then I get a stinker usually in the form of a new version of a make or model I am familiar with case in point: this 2210. For the JVM-4 I am experienced.or so I thought.
Marshall modified the new design, and a 1988 schematic for the 2210.This amp kit comes only with a technical schematic and a wiring diagram. This one came to me in a bit of a mess without many connections.12 user reviews on Marshall 2210 JCM800 Split Channel Reverb 1982-1989 MGR/Dr. I had the 2210 as my main amp for 12.

Since so many things weren't hooked up when I got it I've had to follow the schematic. I used good quality F&T caps on filters and sozos on preamp board. All I did once I got the amp was re-capp the main filters and the preamp board. But in terms of this hum as soon as I turn on the power switch, I have never seen that before.after the standby is put on , sure you expect to hear a hum, but not before.Mine is the later one and is a 100 Watt head I could tell at first glance as this one has the lower value fuses.I've noe double checked everything to the schematic and now will take a bias voltage reading. I'm can read schematics but sometimes have problems if things aren't spelled out or I'm building to a schematic without ever seeing the components hooked up before like with this amp. This amp is just enough different that I'm confused on things I thought I knew and now I feel like I know nothing.There are no layouts anywhere on this model to even get an idea other than from photos which is really hard way to go.
Double and triple checked work to the point I'm starting to doubt even what I do know.Okay I powered up to take a bias winding voltage and get 35.86 VAC (44.80 VDC) right at the post where the bias winding hits the preamp board. Done continuity checks etc. At this point I just can't see what I could have done wrong on the hook up. I may have to go back to ground zero and repower the damn thing, I hope not.
But this thing has a few different aspects that are throwing me off for some reason - or not, and it's got nothing to do with my hook-up and more to do with either a shorted OT or PT winding maybe.But nothing is obvious on initial OHM readings from Primary to secondary and all to ground. I have NEVER had so much trouble with figuring out hook ups. When the standby is pushed on. Looks maybe like someone tried to add more gain to the master maybe.The final reading I got at the rectifier was 387.0 VDC.But for some reason it's blowing the B+ 1A fuse.
The other red wire I have running from the filtyer cap right under the fuses to and feeding the PI. What I'm iffy on is where the inside fuse terminal red wire should first connect to - right now I've got it going to the filter cap next to the one 1/2 wat under the board. I've got the OT/CT Choke/CT and a red wire running to the end of the Fuse as I know should be correct. Starting from each leg of the B+ fuse and the filter caps and board. Thats why I just need to know where the red wires you see in that picture run.
