I'm restoring a battered 2285B and it's coming along. I have it working again and the recap is done except for the main amp and the AM/FM board. In the process I had to remove the power amp transistors to re-goop them I decided to order up a full set of modern replacements and swap the OEM with new just to see if I can hear any different from the OEM to modern. I'm expecting the new transistors this week from Digikey and I'll swap them in. Has anyone else done this? The OEMs are "Fine" according to testing but the right channel HFE is consistently lower than the left channel by 15 points. Even that is above the min of the data sheet.

At the time same I'm replacing the diode arrays on the power supply board with
