Vintage Synth Repair

resurrecting this old thread.

Did anyone ever figure out the best way of mounting the TIP20/TIP25 darlington pair in the arp 2600? They use case style TO-220, whereas the originals (MJE1100 and MJE1090) use TO-126. One is BCE and the other ECB. You cannot just flip them around since they are used for mounting the board as well.

Curious how others handled this. Did you cut traces and rewire or use some other method?

Thanks,

DT
