Useful cheap small tester...

[Nick]

If you look at Section 7, "Known Problems", of the original manual I posted in http://golbornevintageradio.co.uk/forum/...6#pid46386, you will see that even the fully adapted original hardware has problems with some germanium devices, and these Far Eastern knock-offs, wonderful though they are, are built to a price, not quality, so do not include what are generally considered mandatory updates to the hardware.

I would read the section on known issues with the clones, Section 2.5, and see if those can be retrofitted to the eBay cheapies...
