What is it?

pal(not palomar) or maybe a messenger.

it looks like a DSS (digital sport systems) amp.
DSS amps look alot like Stam Comm amps.....but I believe yours is a DSS. I used to see alot of those up here in Canada. I have a few of them in storage.

Alot of those amps of that era used the same boards, boxes, switches ect ect......they are hard to identify sometimes.
I could be wrong...but that amp looks alot like a DSS or StanComm.....If I remember right, yours looks more like a DSS. Alot of DSS amps had a an output xformer with 2 speparate windings...looks like 2 transformers with one stacked one on top of the other.

I think its a DSS

Do a google image search for Digital Sport Systems......or search this forum....there will be some pictures on this forum of a DSS amp that you can find with the forum search engine or google images.

Take care

one of the many generic 100w broadband ss amps of the 70's-80's.all the dss amps i have seen had that road logo on them.
this one is nameless to keep uncle charley guessing as to who was selling them.harder to pin em down.

I'd say Digital Sports. Or maybe LDO (Long Distance Operator). Very little difference between all of those type amps with the stud mount devices.

Digital Sport Sytems is exactly what it is I have 2 of those. There actually supposed to have a label on the front I believe theres a picture of like a road with lines on the face Ide have to dig mine out but I believe there also 100 watt amplifiers.

If memory serves me those trw transistors were 60 watts max....
Between 100 and 125 watts is the most you can get out of the amp...you can also drive them a little harder since they have a resistor that lowers the input drive. But even then the max is around 125 watts
Great amps if your looking for carrier power....
