No perfect matches, but some close ones:

808 MIC or Mixer to Single or P.P. Grid *50/200 10000/40000

for the input. Strap as 200:10k and terminate with a 100k resistor.

Or, you could try this:

560L Collector to Line or Matching 150/600 5K/20K

Strap as 150:5k and terminate with a 47k or 68k resistor

For the output, I would go with this:

842 ** P.P. Plates to Line 5K/20K (6K/24K) 125/500 (150/600)

Work it as SE to line. Strap as 5k (parallel):500 and go!

probably a little lower max output??

But why HAMMOND???. I think it´s expensive and it won´t fit the PCB. I would go LUNDAHL or OEP!
