Default 67 Transistor ignition board repair - parts?

I have an extra t.i. board that needs two main transistors. The originals were GM Delco 1960632 and 1960584 numbers. Does anyone know what these would cross-reference to for current replacements? I could use an empty t.i case if anyone has one collecting dust..Thanks, Kurt

Don't know about replacements for the original components but they make a replacement printed circuit board that is very easy to install. They work great, I believe it was around $100.

Two diodes burnt out in my TI unit left me dead in the water, called Mid America they sent me a state of the art circuit board, installed it in the original TI unit and never have to worry about those old circuits burning out.

I believe the transistors Delco used were germanium. As far as I know, no one makes germanium transistors any more. Modern power transistors are silicon based. The two do not interchange without some minor circuit redesign so there won't be a drop in replacement.

New state of the art board is the way to go and who is going to know other than you since it is inside a housing? As Jim mentioned parts are not available unless you can find NOS parts or used.

You can call Dave at TI Specialty and see what he says. http://www.tispecialty.com

Dave has an excellent reputation, but is $$$. New board may be best alternative as others have stated.

I have talked to Dave at T.I Specialty he was very helpful and gave me some things to check. "Quality Guy". I should consider a new style board instead of repairing this one. I noticed a "new" board has been advertised in Driveline, has anyone tried one of these?? A friend tried one and says he has noticed an improvement in engine performance.
These 40 year old electronics scare me.. Maybe, I should try one of these newer engineered boards.. Kurt

Just do it! I put one in my 64 fuel car and it starts easier and seems to have better overall performance.
