Re: TXE2 Exchanges
I've got loads of those CV9507 transistors here. All made by Texas Instruments Bedford according to the code.
The ubiquitous diode I remember from exchange-days was the 1N2071 - we had millions of the things and coerced them into all sorts of unusual applications [imagine hundreds of the things wired in series-parallel to use the 0.6v-per-diode forward-voltage-drop and let us use 115V equipment on 230V mains! I have STC New Southgate to thank for learning that one]
