IÃ‚Â´m owner of an Organge Overdrive Amp, Model No. OR 80M, which I bought about 10 years ago. Unfortunately the dealer was not able to tell me anything about this amp. The serial number ist 64238. It would be great if anybody would be able to give me any technical information about this amp.

Thank you very much.

Hi Harald, and welcome here.

The serial numbers aren't much help in accurately dating old Orange amps unfortunately, as A/ they didn't keep records, and B/ the numbers don't seem to have been used in strict order of manufacturing anyway. The number would suggest to me though that it was probably a 1970s model, made towards the end of that decade, likely in '78 or '79.

To find out a bit about the OR80M Overdrive you can do a search using the search button at the top of the page - they have been discussed quite a few times. Also this site is useful:

One thing to be aware of with the 80 watter is that they had exactly the same transformer as the 120 watt model. As they run only 2 instead of 4 output valves though the impedance settings should have been relabelled, but weren't always. Instead of 4, 8, 16 ohms (on the 120 watter) they should read 8, 16, (and 32 ohms if all three taps of the output transformer are connected). Sometimes only two were, but anyway be aware that you shouldn't run a 4 ohm load with that amp. See this topic on another Orange forum:

If you aren't sure about that then read around, and please feel free to come back and ask more.

Good amp by the way Harald! I have the 120 watter, and the 80 watter is very nearly as loud!

Andy.

Thank you all very much for your help. I like the amp very much and the funny thing ist that I bought it four about 150 Euro, which I think ist very cheap for a great amp like that.

Well to be fair he DID buy it 10 years ago. 120 some euros is a good deal anyways though. That long ago many nice things could be had for much cheaper... then the craze started and even knobs cost alot now...

Why are Orange amps orange, when they make everyone green with envy?

Hi Andy,

I have another question, if you donÃ‚Â´t mind? What does the M stand for in 80M?

Thanks for your answer.

Harald

Master Volume I believe - the 'Overdrive' models got the 'M'.

Andy's right- the M is master volume

Some do- some don't. One of my heads has the M the other doesn't. They're identical otherwise...
