Can you identify what this is?

Works for me !
Can anyone one identify what this is? It looks very much like a Dynaco preamp but the switches on the left side are not familiar to me. I have a Pat 2 and 4 but they look different. It has no manuafacture markings and I can't find anything simular on the net. I have looked. :scratch2:

Thanks!

a Dolby processor

It is built into a Dynaco chassis but I think it is a Dolby noise reduction processor for use with a tape machine..

From what I can make out by the written labelling on the rear of the unit,and the type of jacks down to the left it used an outboard supply or was slaved to a pre-amp for power..I cannot read the labelling on the front but it most likely is a processor..

Could be a rare item but also could be a DIY..

I did. Has lots of wires, resistors, switches, a couple of big caps . Does not help me in knowing what it is. :scratch2: I was hoping someone Would recognize it as something they once had. Guess not.
 
It is in no way a Heathkit. It is an ex Dynaco and somebody made something else out of it.

Like Matt said, a Dolby processor or the whole thing could just be a switch box for putting external devices into the chain.

I see jacks for a reverb in and out too.

Just a home made, one off deal.

The odds are probably astronomical that anyboy else would have the same exact thing.

Hmmm... looks like maybe a preamp, plus dolby and possibly a tape head amp, plus a reverb tank drive and recovery circuit, and it looks like maybe no internal power supply. Or, maybe it's nothing but switches and mixing circuits. Could probably tell at least a little more from an inside pic.
 
It's probably a modified PAT-4, judging by the remaining silk-screen lettering, but I'm pretty sure Dynaco sold blank unpunched front panels for a while. Someone could have created this from whole cloth.
