Hi.
Well I have now been able to sort out the the brackets that hold the glass in place and I think I can devise a tool to get the really inaccessible last screw in place. I have now fitted the switches and controls and improved the routing of the cables. The set has been fully tested and a couple of valves has brought up the performance to a very good level indeed. The downside is the 6X5G rectifiers, the one in the set is down with HT being 50v less than it should. I have 5 of these in stock and they all flash internally, a quick cobbled up EZ80 is fine and restores HT to normal.
I think I'll make up an adaptor plate and fit a B9A base and the EZ80 as a permanent solution.
Using Mullard valves gives improved performance rather than 6K7/8 in RF and IF stages.
The job to repair the set was involved and really fiddly at times and not one I'd like to tackle again but the end result is good, the BFO & X-tal filter work well and for the valve line up it is sensitive even at 31Mhz.
