Jez, I guess you are a hoarder too!

Incidentally, for anyone considering building a Lentek head amp for themselves, the 2SA1085 and 2SC2547 with a source impedance of 100R both have a noise factor (NF) of around 0.5 dB and they are effectively operating in parallel for noise purposes, so the averaged noise contribution would be less than 0.5 dB without a cartridge connected. The noise level would rise slightly with a low impedance cartridge connected but would still be acceptable. These transistors are not current production items but they can still be sourced from surplus outlets.
