Toshiba T2295A, High Power Density 1.2A Boost Regulator

General search shows a couple of thousand still out there. Before you order any, have you tried cleaning all the wire harness connections, grounds, and re-soldering on the circuit board? I cured my bouncy (NOS) tach of the jitters by doing that. Anyway, here's what my supply chain shows for the T2295A:

OK. No, I have not removed one, but I could pop it off one of my donor boards and let you know.

Thanks, it would clear up the blank spot in the resister chart. I arbitrarily assigned #24 to that spot, but I would like confirmation.
Also, if you could check the location numbers on some caps, that would clear up some questions about their numbering.
If you could do that, I will describe their position in relationship to identifiable components. (i.e. component locations that are clearly labeled).
If you are willing to do that, please let me know, and I'll make out the list.
Thanks, CZ

You know, between all the variations of boards, the part position numbering will be different. Even the total parts count will differ. That said, here are the variations known to me:

First, on the left is the '81 and up, with the advance built into the IC. On the right, pre- '81 with TO-3 output transistors.



Here is a pre-'81 using TO-220, Go figure!
