Took my 800B out of mothballs but could not locate speaker so rigged up a jones plug with a pair of resistors for the field, the jumper to turn it on, and and some speaker wire to a bookshelf…Continue

Perhaps this is normal but the shadow on the FM eye seems to be modulated whereas the AM shadow is steady.Is this normal or does it represent a need to match the demodulator's load resistors or…Continue

Still looking for Pointer Dial Philly and don't neglect your prostate!

To all the guys: Have a thorough prostate exam! No preaching here or scare tactics, for your own sake and for those that care about you, see a good urologist for a thorough exam. Instead of working on radios I have spent the last couple of years dealing with a prostate situation. My wife became very ill about the same time as my urologist found cellular changes in my prostate and my PSA had jumped from 2.5 to 8. But I had to put it on the back burner as I had enough on my plate with my dear…See More

Hello Mr Sloane:  my apologies to you, i had a store to close and move everything to storage. it was quite an undertaking. i will be checking my E.H. Scott messages tomorrow, and maybe we can converse about the Philharmonic that i have for sale if you are still interested. the photo you have of my philly is the same one i am selling.  You see, i am 75+ years old, and the move was overwhelming to say the least.  I wanted to bring this one back to life, and what i mean by that is, i closed a electronics store recently that was 71 years old, we repaired electronics and also tube mono/stereo equipment,  we always brought our electronics up on a variac and never ever plugged them in to see if it lighted up!!   so, i have never plugged the philharmonic into a wall socket.   i did have one member tell me after i gleefully told everyone of my find, that he thought maybe all i may have to do is change out the capacitors, and he also said, and i bet it will work.   well all i had time to do was to test a few of the tubes and all that i had tested on a tv-7 army surplus tube tester after it was calibrated professionally were all excellent. i may have tested about 15. then i had to get back to reality and take care of my customers.    so, i am not sure what all i can do for you, but i am available to talk about my baby.  oh, by the way, i hate the use of philly to describe this radio,  A 1939 Philharmonic deserves a little respect after all of the world events it has reported on.  this Philharmonic was 3-3/4 old when i was born in october of 1943.  after i reported the serial number to mr. Braithewith he thought it may have been built around December maybe as a Christmas Gift.    well thank you for being a friend of E.H. Scott's Products.  

Don Baker
