Music Reference RM9 Mk.I schematic

[A1008]

Is there anyone who have the schematic for the RM9 Mk.I?
Made some new pcb for this one. Double sided and with 70um tracks. The silkscreen is marked with the resistor values I found on the old pcb but I`m not sure if they all were the original ones. Got 4 left so if anyone is interested I could sell for the actual cost.

I have the service manual, PM me. Awesome amp! The original boards were iffy after a few years of heat. I'd like a board.

It's been a long time, but I just saw this. Is there any chance that you still have a board or two lying around?

 

[A1008]

Maybe I have one left so let me check.

 

[hopat]

I apologize for missing your response. If you find the board, I'll definitely snatch it up. I actually could really use 2, so much so that I would even consider paying for a new run of boards if you only have the file remaining.

 

[A1008]

I couldn't find the board I thought I had left, but I`m actually making a new and improved version. Its not been ordered yet cause I still have some details left to work on. It may take some time getting the board made cause this Covid 19 thing is effecting everything from manufacturing, shipping and custom service.

 

[hopat]

I have time. Please keep me updated, and like I said, I'm interested in 2 boards.

I would be interested in a board as well.

 

[A1008]

I`m ready to order the boards so if you still are interested, let me know.

Is it ok for you and hopat to pay upfront for these boards? I`m ready to order but only if both of you (and hopat) actual want them.

 

[randyman65]

How much are they? I’m willing but need to know cost first.

 

[A1008]

$35 inkl postal service if hopat takes his two boards. You can have the Gerber files for free if you think you can have it the made at a better price in the States. No problem.

 

[randyman65]

That sounds fair. I would like two boards. PM me for contact info.

A1008 I PM'd you.

Got it and gave an answer. Thanks.

I just found this thread. My RM-9 mk1 has been on the shelf for years. I would like to get some music out of it again. Do you have any more boards? I also need a copy of the schematic if anyone have one. Thanks in advance!

 

[A1008]

Yes I have, two of them. One of the first version I made, the one you see in #1, and the final version, say rev.1. The only difference, as I can remember, is that rev.1 has silk screen on both side.
