I saw the brocures there but did not see any schematics there.

 

[Netlist]

No, they don't show or have schematics but they could know someone who has..

I am surprised info on these machines is so hard to find!

 

[dukeofearl]

Did you ever find schematics? I'm in the same boat

 

[Zero Cool]

Nope, I can only find some sales brocures. I cannot find ANY service related info what so ever! I have a mono transport. and I found a set of control electronics. but no record/play electronics. no rack panel to mount the transport controls etc. Should you find anything, please keep me in the loop and likewise i will post here if i find anything.

 

[dukeofearl]

Will let you know if I find anything! There's just no info out there about these things.

 

[Zero Cool]

from everything i have read, they were not great decks. even RCA studios removed them and went with Ampex decks i have read. they must have been really bad for this little info to exist.

 

[dukeofearl]

yeah it's hard to tell with so little info. stephen sank, a well-regarded tech, thinks that the rt21 is the "best 1/4 reel to reel ever made."

 

[dukeofearl]

also, i wrote to him and he sold his years ago and doesn't have the schematics

@Zero Cool, just created an account for this.
I just picked up an rt21a and I got a manual with it as well. Its got all the stuff you want in it.
I need to digitize it, I’ll post it for you once I do that!

 

[Zero Cool]

OH YES YES YES please!!!

@Zero Cool @dukeofearl
Here's a G Drive link to the RCA RT21 PDF Manual.
The last couple pages look like they were foldouts. May be good to have it printed for those pages.

Hello, Zero Cool. I am from Paris - France. About ten years ago, you had a black ARC DAC7 for sale with, in addition, a silver front. I think you sold this device a long time ago but do you still have the silver facade? Thank you for your response. Kind regards. Jacques
