Hi. Most of the work is now done, at a later date I'll substitute an EM34 instead of the rather down EM4 (NOS). I've replaced the perished speaker cables and since taking the pictures tidied the mains cable and added a filter cap, this helps to reduce the tendency for modulation hum.
One of the biggest issues this set had was the trimmers, they are ceramic and have an odd arrangement for adjustment, nearly everyone was faulty, corrosion seems to have killed them, having a box of modern trimmers (2-30 & 5-55pf versions) I have tacked these on to the originals after removing the corroded parts, a second realignment was carried out and the tracking on all bands is uncannily accurate.
Unfortunately the set is now not original and the chances of robbing another for the parts is highly unlikely, due to this I have not restuffed the capacitors.
My feeling is that this rare set has now a new lease of life and once my friend who has taken unwell (got the cabinet back unfinished) who was going to refurbish the cabinet is all done this set will take pride of place in my collection.
I cannot praise the set enough, the sensitivity is like a set with an RF stage, on selectivity position 1 it is better than I previously thought. My local on 1035 usually floods Downtown radio (Belfast) on 1026Khz and 1.7Kw is perfectly listenable.
So this has been a really great set to do and the significance of the set being made in 1941 to me is really important.
Once the cabinet has been done I'll post up the pictures.
