As well as straightforward repairs, we also develop modifications to allow the fitment of alternative parts where the original is no longer available.
One such item is our replacement ovened crystal reference oscillator module for the 2955. This replaces a failed original and drops straight into the original footprint. The only modification needed is to replace a resistor with a wire link, or simply bridge it out.
One of the other issues with the 2955 is that the line output transformer (LOPT) fails and is no longer available. The LOPT supplies the EHT to the CRT as well as various auxiliary supplies and (in the case of the 2955) the vertical scan drive, as a result, we developed a conversion kit using a new old stock LOPT which we managed to obtain in quantity.
These have been very successful having used many ourselves and sold around 50 kits with no reported failures. Unfortunately  supplies of the LOPT have now dried up and we only have a few remaining.
We are also working on a replacement for the LCD used in the 2945, 2030, 2040, etc. More news on this when we have it.
