After some struggling, I was able to locate the scarce OM-2045 Philips hybrid amplifiers I needed for my Marconi 2955A repair. But, of course, I needed to buy too many of them to get the two I wanted!. So I have for sale the extra units. You can find info about them here:
Hope this helps to fix some other Marconi 2955/2955A units!
