S-Pultec PMEQP-1a3 what are these transformers or parts in here? DT-171

Hi,

I bought this on Ebay and it sounds quite good, but I would love to know what components / schematic was used in case I want to modify it later.  I see DT-171 transformers it looks like?  Any info is appreciated!  I might have a tech look at it and see if it would be worth it to install some UTC's or even add tubes.

Who makes that?  Also, what does the front panel look like?

It looks like the solid state pultec circuit, which sounds pretty nice.  The original transformers are hs56 on input and output.

If it sounds quite good than put the lid back on and patch it in.

The PCBs look like my poor man's EQP1A design. Documentation is here:

in the PMEQP1A folder.

They don't look like hs56 transformers to me or are they?

What's the DT-171?

Thanks so much,
Eric
