Wow, it has been 50 years since I had an SX-115. Great receiver. The only thing I can think of is that the narrow BW filter is no longer tuned to the 50 KHZ last IF stage. 73 – Mike Mike B.

I am working on restoring an S-38E and would appreciate a clear reworked copy of its schematic diagram. ?I have found some scanned copies but none are clear enough to read all of the component values

Hi all, Just got my "dream receiver"...SX-115! It is a beautiful receiver inside and out. After careful power up, no hum, and it works, mostly. The sole issue signal in the 0.5 kc bandwidth are about

Dave, Thank you very much for answering my request. ?Y es I still need two knobs. ?Yours look like what I need. ?Please pm me with how much you’d like for the nicest pair of which you don’t

Hi Bill , I have several of them, contact me if you’re still looking for them. Dave KB6MBC

Adam, I did a similar project a few years ago. In the HT41, I replaced the 15 amp circuit breaker whose contacts had been chewed up by years of abuse. Also,remove the on/off current from the

I have a SR-150 with PS needing recapped. Also will be recapping my SX-117 and HT-41, then seeing what else is needed to get them on the air.

This serial number HT-9 appears to have some unusual things such as the meters and also internal marks on the chassis. The normal nomenclature on the crystal and tuner sockets is different from my

Who knows know long the poor thing lived not working because some guy stuck that tube in that socket .

The "beast" lives! :)? THANK YOU guys. Replaced the known incorrect tube with a proper one,brought it up with? variac and dim bulb again, and at 75V I have WGN radio. Good enough for today,

Howard, Download the S-38C manual and the tubes are listed in the SERVICE PART LIST page. V1 is 12SA7 Converter V2 is 12SG7 IF Amplifier and BFO V3 12SQ7 or 12SQ7GT/G Detector and audio amplifier V4

Correction: second tube is a 12SG7, fat fingers. The tubes are typical "All American 5" meant to work from AC or DC at about 115 volts.

You want tubes that all draw the same heater current so that the heater voltage for each tube is correct.? The 6SK7 heater draws 300 mA, not the 150 mA of all of the other tubes.? The heater voltage
