Delta 100 manuals.


I have a delta 100 amp and am hunting any documentation.

Owners manual and service manuals would be great, but I’ll take what I can get.



Howdy Miguel,

Thanks for posting and welcome. Awesome to hear you still have one of those old Delta 100s.

I’ve attached some schems for the amp as pdfs. Let me know if you have any trouble seeing them.



It’s a wonderful amp imho.

Full of life and subtlety, effortless and open.

This is the only one I’ve ever seen and I’m keeping it!!!

A question.

if I want to run it on 220v do I remove the two jumpers labeled 110 on the schematic and install the jumper labeled 220 and apply power to the current power locations?

I’m considering running a dedicated line and it might as well have both legs.



It’s back from alignment…

the speakers are back.

i got a rotel 975 CD player (a beautiful piece)

amazed again at the effortless and transparent sound of this instrument.

icant stop grinning.

Is went silent last week…it’s back in the shop.


Does PS audio do repairs?
