Hi everyone,Hope you are managing to keep warm. We know that you are experiencing exceptionally cold temperatures at the moment and our hearts go out to you.
In a recent post I think I mentioned that I had bought a Midwest 7/36 at our local swapmeet as a non goer.So it was up and onto the bench today.A few preliminary checks showed the power transformer,speaker field and output transformer were all okay as were all the valve filaments (58, 58, 58, 55, 2A5 , 80 and 56 osc).Someone had kindly replaced all the wax caps and the electrolytics and a good number of resistors too.Not much for me to do really ,but nonetheless smiles all round when it burst into life.Midwest sets are rare here,the object of envy as we read our vintage Popular Mechanics especially those multitube behemoths but this one has the more modest tube count of 7.Big shout out to someone named Mike Simpson who has redrawn the schematic and possibly uploaded alignment info as well. Someone had also replaced the e.m. speaker as well,this time with a field of 2.5k instead of the specified 1.5k but it still has oodles of volume.Nice radio and a tribute to American radio engineers.
