RS-1500 preventative maintenance
« on: March 29, 2013, 02:09:46 PM »
I recently dug out my RS-1500 I got second hand in 1984. It was hardly used by the previous owner. I used it some but not extensively. It was stored in a rack mountable anvil like case so it's not gunky just dusty. I probably hadn't fire it up in some 20 years or more.
I took a chance and fired it up using a homemade variac type of device and brought it up to power slowly. I didn't hear anything explode so I may be ok for a bit although I would rather do some preventative maintenance before anything does go bad.
I believe I have a link to download a service manual but haven't printed it out yet.
Can someone recommend what preventative maintenance I should do.
I'm assuming open it up and check all the Caps especially in the power section
Any advice would be great.
This is my first post. I have been lurking since I recently broke out my echoplex again. It seems like every one is very helpful around here
Thanks in advance

 Hello, I hope it's not too late ...

I would suggest changing all the electrolytic caps .

Clean any dirt/dust out.

deox all switches and pots.

replace the two counter belts, they are probably in bad shape, you also may hear a squeal from the counter, I used a toothpick and some lubricant to correct that..
Check the condition of the two roller guides, they might need to be replaced. The DIY kit here is a good start.

Buy/download the service manual.
