Dear fellows, after several years of faultless operation the tube of my ACOM 1000 had to be replaced. My good friend and very capable technician, Tasos (SV8YM), offered to to do the job. The photos show characteristically what he found out as soon as he took the cover off. Everything was covered under a huge amount of dust. Fortunately the dust didn’t affect operation.
After careful removal of the dust and several hours of conditioning the new GU74B the ACOM 1000 was fully operational again. Many thanks Tasos.
Merry Christmas to all.
