Re: Writing a test equipment theory and repair book?
I mentioned the nixie tube as I remember seeing a frequency counter in my dim and distant past, possibly made by Solartron or Racal.
Also do you require a circuit and photos for the Antex TCSU1 temperature controlled soldering station? Am currently repairing mine and have taken some pics of the inside etc.
Another item, that I have is a Kikusui 100Mhz oscilloscope, which uses a dual tracking power supply chip and I do have a service manual for it.
