I have 4 ECG160 transistors (2 that are unused and 2 that look like they

send them along if you think that these will resolve your problem. I
doubt that I will ever use these.

Thanks for the advice and offers of parts, guys; much appreciated. On
reflection I decided to replace with silicon. The purists would go to the
trouble of hollowing out the old transitors and fitting the silicons
inside them. Fortunately, I'm no purist. :-D


No problems here. If you want to use the ECGs to verify that everything works prior to "upgrading" to Si, the parts are available. These are small enough that they will fit into a small padded envelope, so shipping will be next to nothing.

Let me know if you want them (no charge).
