kent version bow wow yoy yoy

[pinkjimiphoton]

hey guys,
picked up the kent version of the schaller bow wow yoy yoy, aka the kent bow yoy model 6402.
it APPEARS to be intact, but someone was monkeying with it at some point and appears to have tried to hook it up as a volume pedal. this is one of the ones with the dual inductor and a single gang pot for the sweep.

anybody gotta couple gut shots they could send me please? since botophucket screwed the net last year, most of the pictorial info seems to be gone.

i'd like to try and ressurect this beastie if possible. jusy hard to tell whats original and what's not... so easier if i can see how its wired so i can restore it.

thanks in advance!

schematics are useful too, i assume its the same as the schaller, but just to be sure, i figured i'd ask.

i have a spare shell for one of these too i may do something with, unless someone needs one.

thanks friends... rock on!

the bitch is the 4pdt is gone.. i have some, but the pinout is a lot different from the old ones. thats why i am hoping to find a decent close up of the wiring and stuff.

really appreciate the help! i messaged dino about the pinout for the 4pdt, hopeful he can help me suss it out.

I used to have one of these, 30 years ago or more.  Jeez I miss it.

Here is the correct schematic of the first edition, Panzer tank, art deco models;



Transistors vary from year to year. BC239's have been used as well.

The bypass switch is a weird sort of double DPDT. Here is a picture, I've drawn in the poles and shunts.
