Hi Brandon,
I had a chance to play around with a 34E that was at a local thrift store many months ago. They were looking to get $1,000 or so for it but it did have a very nice 145 Leslie with it. It had a number of external speakers and it appeared to be all connected correctly but it wasn't in top form even though they said it played well before they moved it. I've currently got a couple of Trio's (321B and a 322 Deluxe) and in terms of size it was certainly a larger instrument. The pedalboard appeared to be full AGO spec and the console was quite a bit wider than the Trio's and it really looked like an old pipe organ console. Two swells and a crescendo pedal, setterboard combination action with moving stops, toe studs. The insides were definitely old school with lots of key contacts, solenoids and relays very similar to my old Allen Theatre Deluxe. I'm guessing that the 36E is similar. This particular 34E looked to have a few parts and wires that sure didn't look original. If the one you're looking at has been "improved" it could lead to some challenging troubleshooting sessions. Even the documentation on my Trio's isn't spot on so I'm imagining that you'll have to do a fair amount of wire tracing on the 36E even if you can find a set of schematics for it. Not a big deal unless you're paying a tech big $$$ to poke around at it. I ended up passing on the 34E since it wasn't a big enough jump in organ appeal for me, I'm still holding out to find a decent Olympic 333 or a 340 :^) The folks at the thift store thought that the other interested buyer might have wanted it to use the console for a VTPO.
I wouldn't let the germanium transistor design alone cause you any special concern. I've got plenty of them in some of my older organs and so far have had only one failure and that was a transistor that was used in a sustain circuit that had a lot more stress on it than the tone generators. If you did run into a failure in an older transistorized power amplifier I'd be tempted to just replace the amp with a newer one since most of the old power transistors don't come cheap. You should be able to find suitable replacements for any transistors that you might need to replace.
The 37E had too many tone generators to fit in the cabinet so they put them in a good size cabinet that I believe was connected to the console with lots and lots of wires, like an old pipe organ. I'm not sure if the 36E uses a similar design. If I was closer I'd definitely take a look at it, the price seems quite good if it's complete and in reasonable shape.
I too love the sound of the older analogs. Now that I've done a few things to my 321B (speakers, amps, reverb, adjustments and a couple other mods) it's very pleasing to play. The only downside is the typical 70's plastic keyboard which just doesn't compare to the wood core keyboard systems on my old Gulbransen's and 322.
Let us know if you go take a look at it and if you end up picking it up.
