Hey AV I hoped was a little help there Bro! I never did understand why they did that on the 4100's. Don't tell anyone I knew anything about an amp made after 1983 LOL It will ruin my reputation as being an old fart.

Can you take a look at this thread, I think you may be able to help us with a little wiring question on an output transformer, thanks bro.

Viking the sound bites are up. http://www.marshallforum.com/cellar/...om-builts.html

Yes I have clips of all three amps. Can we host them directly or do I need to use an offsite? As far as final ready to play, it takes a month including building the Poplar wood boxes for a complete job.

That custom built stuff you got looks pretty well put together. If you ever load any sound clips up I'd love to hear them. How long does it take typically to complete an amp project like that?

Hey There Viking, I put up some pics of my custom built gear if you'd like to have a look? Check my album.
