Ladies and gentleman, boys and girls, and children of all ages: For those of us with the awful habit of restoring vintage equipment and who often have a hard time finding these, they fit Dynaco and similar devices. Peter WIeck Melrose Park, PA |

Update: These fit as-found in a latter day SCA-80Q. I had to file them down a little bit to fit into an SCA-35. Fastener spacing is dead-on, and there is plenty of clearance inside in both cases.

Just struck me - be sure to do the TIP-Mod on that device before releasing it back into polite society. Most especially applicable to Jefferson Street models (19121 zip-code). And replace the 2N3055 output transistors with 2N3772 devices, matched if you can. It will be a very different amp thereafter.
