Hello: Client asked me to work on comatose radio inherited from grandfather. I have worked on dozens of philcos telefunkens RCAs GEs and such but this is first time tackling a EH Scott. The…Continue

"A scan of the station finder wheel can be found here... https://ehscott.ning.com/photo/albums/allwave-deluxe-station-finder. Copy onto manila folder stock, cut out, punch a small hole in the center and fasten the two parts with a brass…"
"That finder wheel is not among these paper items. I can figure it out I expect. Client is not likely to try for SW DX-ing! Thank you."
"In Ohio, reception is variable on those 3 frequencies of WWV. The 12 tube Allwave Deluxe dial for the 3 shortwave bands is just 1 -100 scale. (the 1934 model FIFTEEN for short wave is accurately calibrated in MC on the dial strip.)

"I am getting our uppermost AMs here on the low SW band even without the optimizer connected. One should be able to get the WWV at 5 10 15 n 20 mhz is that right? "
"Test SW at night, and use as long a wire as you can for the antenna. It should pick up AM stations on the first SW band at the low end (it starts about 1.5MHz), there should also be stuff in the 6-10MHz range. Tune SLOWLY, the small SW unit in the…"
"David I must think hard about this wunderlich business. If I got one, and I appreciate that you might provide one, I would have to undo the modification done by previous person. Right now the radio is tuning and receiving and sends line…"
"From the info archive here, print off an owners manual to give the owner. There is several versions. Each has a tube layout for the receiver about in the middle. fFnd one that has the same 1st detector as yours - either showing a 57 or 58 tube.…"
"With today's higher voltage, the high-low switch should be which ever position dims the dial lamp a bit. Hence, the low position keeps the B+ at a desirable lower voltage by maybe 15 volts or more.
If Kent does not have a good…"
"Hello and yes I am sure that switch is set for higher incoming but will double check that. And yes the big resistor drops down each step to zero at the bottom. I had not thought to look on here in archives for more data. Thank…"
"The B+ is a little high (should be 225-230VDC), but today's higher line voltages probably increase it some. If there is a Hi/Lo switch on the PS, be sure to set it for High voltages. Check to be sure the B+ divider resistor is good all the way…"
"The only schematic I have found provides no voltage information. Whoever put this 6dj8 in also put in a little 6VAC filament xfmr just for it. This wunderlich has no plate cap and is not marked as A or B. Incoming B+ to the tuner…"
"The Wunderlich tube design and application for detection and automatic volume control was developed by Norman E. Wunderlich. The first tube designed for AVC was put into production by the Arcturus Radio Tube Company which explains the…"
"Hello Kent: I will not literally trash the electromatic. If the client does not want it, we can find a way to get it you. It does turn 78 and even 33 and it tries to cycle when manual reject command thrown but it will not auto trip…"
"I can probably help with a 55 or even a Wunderlich (I need to check what I have)...
Please don't throw out that turntable - the early ones are hard to find - I would be very interested in it, even if not working.
Kent"
"Updates: the blue tinted wunderlich in here has open filament. The 6dj8 was put in to perform some detection. We are abandoning this electromatic record changer. The client wants a modern turntable for 33 n 45 which will drop…"
