Moog Music Forum

Hi anyone know where to get the above.
Best regards.

Repairing a 73 Minimoog and need a VCF board , populated or not.
Failing that , is it possible to use a model D reissue board , assuming they are available as a spare part.
Any thoughts.
Best regards

Hi Tom , that's the cct I'm using to check Vbe matching, The error you noted has been the subject of much discussion in the past on a few forums----the conclusion by people way smarter than me , was fixing the error did little if anything to the test results. Maybe Bob was right. The real reason for...

Hi ,I'm repairing a mini contour / keyboard pcb. Q9 was snapped off , so I've decided to replace the pair --Q9 & Q11 with 2n3904/2n3906 pair. The footnotes on the schematic state that the PNP should be matched to 10-20mv lower than the NPN @ 200MA. With the transistor matching cct provided , how...

Hi all , refurbishing the above board and noticed that q9 and q11 are matched with the pnp 10-20mv lower than the npn at 200ma.
Is this a typo ?

Little help from an EE.

Hi thanks for your replies. I'm almost embarrassed having asked the question---it was a no brainer. The Perspex ones did belong to the contact strip. The thick wood blocks go to the rear and thin blocks to the front--simple. Installing the Optokey was a walk in the park , all the photo sensors neede...

Hi All , just recently installed an Optokey and while reinstalling the keyboard , got a little confused. Kept notes whilst dismantling the keyboard , but damned if I can find them. The attached photo shows 3 pairs of blocks---3 different sizes , 2x wood 1x Perspex. Not sure what goes where-----I thi...

Hi Alien diablo----try missing , that'll do it every time.
