Well I successfully cloned the Beat Club ORST 50w amp that was used by Free, Sabbath, Humble Pie et al.
I have some pics of Andy Powell giving it a test recently (albeit through my Marshall cab) if anyone interested?
My next project is a Matamp 2000 with RS Deluxe OT and HD Mains. I have all the parts but am lacking an accurate schematic. The only schems I can find are the cathode biased reissue. I can work a lot of it out from the pictures and the investigations of the ORST but if anyone knows of an accurate schem I would love to see it.
This is the one I am going to build:
Thank you to John Chambers excellent site chambonino for the images.

This is what the ORST 50 sounds like

I can't help with schematics but I'd love to see the pics of Andy Powell playing your ORST clone.
Gut shots of the clone would be cool too.

I will post pics. Just need another host since my Photobucket direct links no longer work.
Can't seem to get my cloud links to work either

Found this short clip, I think Andy did this on his phone. I would love to have a clip of him playing some signature riffs through a spectacular custom made Flying V :

It is playing through an Alex attenuator on a single click down through a quad of pre-rola G12H30 75Hz T1217s (same as early Oranges) as my old Orange cab has early 22w Fanes and does not have wheels.
The amp is on about 8 or 9 on the volume hence the break up with the Les Paul plugged straight in.

A stunning build! So you ended up with 50w version instead of 100w?
Did Mark play the clone or the original in the clip?

Only clips of Mark playing (Andy did the recording on his phone)
I was to busy watching and listening to record Andy.
Good news is that WA will have a full Orange backline for the coming tour which is fantastic. I hope I am not breaking news but both Andy and Mark will have two mini stacks consisting of an OR100 and a Rockverb each and each these will be feeding two 2x12 Orange cabs each (I think more portable than 4x12s).
So total of x2 1970 OR100s and x2 Rockverbs and x8 2x12s, the new kit will be supplied by Orange!
I look forward to hearing them and hope as many of you can make it for the tour to see new and old Oranges used to their full potential:

Ok, so here is a proper schematic drawn based on two different mid 60's
Matamp 2000s, one sent to me, the other one I have derived from the pictures of the pictures I showed above. As before if anyone sees any mistakes, please let me know and I will correct them.
The depth pot only has x4 connections although the pot is drawn as 6 position.
I have put the boost pot down as 50k as that is the value on an ORST although the layout sent to me shows the boost to be 500k.
