(ET) E-15 card #1



Mike,

If you have to replace components on card #1 here is some info:

Q104 and Q105 are 2N5309 (NTE 128) NPN Silicon.

Q103, 102, and 101 are 2N2646 (NTE 6401) UJT silicon.

Diodes are NTE 125.

SCR replacements are NTE5455.

I was able to purchase all these parts from local Electronic store.
