Super rare find today! Planar SR2100

Wish I could...I would like to get a hold of a set of paperwork,manuals etc for the Planar sr 2100 too if anyone could help us out.
Picked my unit up a few months ago and am quite happy with what it puts out.
 
AvalonPen, I have a SR-2100 and would love to have scans of the manuals,paperwork etc if you could do it.
Hope you're still a member here.
Apologies for resurrecting an old thread but these units are pretty limited for info because of the short,yet interesting history.
A friend gave me the unit and I was pretty taken with it's initial performance.
I bought it from him :)
 
Add one more Planer sr2100 owner

Got this given to me and can't add much to what has already been said in this thread.
This would be cool to restore to it's former beauty but I think replacement knobs will be impossible to find. It looks like there are also a couple cracks on the plastic lens.

Anyone make contact or score any of the user or service manuals or scans for the . I've got the SR-2100 Receiver and it's been in mothballs for a few years.
I'd like to bring it back to spec if possible.
Then, I can give her a go.
 
I have a Planar SR-2100 receiver from 1977, anyone have an idea what it might be worth? I have the original manual and documents to go with it as well
Welcome to AK

Questions about value belong in Dollars and Sense.
 
Found this receiver at my local Salvation Army store today - I grabbed it as they were bringing it in from the back. I almost passed on it because I have never heard of the name "Planar", but this receiver just had something about it that spoke of good quality: nice wood case, very heavy, solid rear plate, decent speaker connectors. I plugged it in and while none of the lights came on, the stereo signal meter would move as I tried to tune stations. So I decided to take a chance and paid the $20 they were asking for it.

The thing must weigh 35 pounds - its a b*tch to carry! After opening it up and replacing a 3A fuse, everything lit up. It is loud, and surprisingly detailed. Superb build quality, almost looks like it was built by hand... the stickers on the bottom have a lot of hand-written info. It has large caps that are laid on their side (I never saw that before). I don't know the wattage - but I would guess it's probably around 60-70 watts. It has a large power supply.

Based on the info I found in the threads below, it looks like the Planar units were more or less "experimental", and may not have ended in stores at all. They were manufactured by Electrohome in Ontario.

I am posting a few pics of the guts and labels, and will add more once I am done cleaning & lubing and the unit is back together...

Hello Ben,

do you still have it? I found one on the curb missing the output transistors and main filter capacitors. Can you please tell me the Motorola part number for the output transistors, better yet can you take a photo so I’ll work which side is npn and pnp?
TIA
Dave
 
Hey there. I was wondering if you still have your planar sr2100? How do like it? I'm a owner to!

If you saw my posts I found one on the curb missing the output transistors, can you take photos of the heatsink with the output transistors and what is the Motorola part number?

Sorry I no longer have it, sold a few months ago. I did enjoy it but it wasn't getting any time in the rotation anymore, so passed it on to a fellow enthusiast. I went through my old photos and could only find one where you can sort of see the transistors. When zooming in, it looks like the part number is AA 601-34. Cheers and good luck.

The service manual is available in the AK database. However the transistor #s are all Electrohome part numbers, not sure what equivalent ones should be.
I've spilled the guts on mine to recap and measure resistors.
