Vintage Synth Repair

Hi fellow analog fans. I'm troubleshooting my 200 and need to see if
any of you know the specifications of D1, D2, and D3. All are the same
type of diode. The manual I have has several copies of the schematics
and different Wurlitzer part numbers (different periods in the company
life I suppose). All three carry the same number in one listing:
202050. In another D1 is an 11 0769 where D2 and D3 are 11 0771.
Anyone have current and PIV ratings for them or industry part numbers
for replacements? 

I also have several sticky keys. I've read the manual about easing
keys and wondered if anyone has had to do this and if the suggested
tool is indeed readily available. Thanks for reading.

Oh yeah...anyone replaced the power jack with a current standard 3 pin
jack?

Thanks for the reply. I've got a friend who does piano repair so I can
ask him who carries them here in Atlanta. Never had to do piano action
work before so this will be something new. I'm not going to replace
the power jack with the original. I'm going to use the standard 3 pin
jack that most electronics (i.e. computers) use. I remember being on a
gig with someone who forgot the power cord for their 200...don't want
that to happen!
