"The latest update is that I substituted some of the spare tubes that I had (58 &57) and improved the BC reception in particular at the low end of the band. I restuffed one of the coil capacitor combinations (on the back wall of the chassis) with…"

"Here is an update on some additional progress. Using spare 58 tubes I started substituting according to the guidelines in the AW-12 literature.  What I found was a nice improvement when 2 of the 58's in the IF were replaced.  I also…"

"David and Norman Thank you for the replies and information. It appears that the AW-12 Deluxe here does not have this. Have a great 4th of July."

"Except possibly for some of the last ones made, the coil wheels for the AW-12 Deluxe did not have the felt bars for cleaning contacts. Norman"

"You can't miss the two felt blocks. Both attached to the coil wheel between certain coil wheel contacts. Dark red and 1/4 inch thick riveted to the coil wheel - so as to wipe the spring loaded, silver plated contacts when turning the band…"

"David I've checked voltages and all appear to be reasonable meaning within +/- 10%. With the 5 position sensitivity switch there are of course a couple more readings than those listed in the documents on the archives. The surface of the spring…"

"Again, thank you for the interest and sharing the information. The contacts on the coil wheel have been cleaned with alcohol and the switch in the antenna coil can has been cleaned and has been tested for continuity. Cleaning the contacts on the…"

"Turn the band switch several times so the built-in the silver polishing felt block wipes the coil contacts several times. Also work the band switch off the broadcast position and back on a few additional times. Also, clean the contacts on the coil…"

"Dave The radio has the pedestal speaker. On the round socket to the speaker one pin goes to ground and the others have wires. On the rectangular socket all 6 have wires. We've been having a lot of electrical storms but today we got a break and…"

"Chronology observations and a question. My earlier AVC model DELUXE (small serial number tag) has the 3 position sensitivity control and my later version (large serial number tag) has the 5 position control. Not to say the the serial number tag was…"

Lars Edwards replied to Lars Edwards's discussion New to Group - All Wave 12
"In looking at the schematic in the archives for the Deluxe with AVC there is a significant difference for the sensitivity switch. I know that running changes were made and I've outlined the differences in the attached file. Thanks in advance…"

"David Thanks for the information. The Napier cabinet is a very nice design and this one needs a little work in particular around the bottom.  I do have the antenna tuner as well. This is the AVC model with the Wunderlich tube. I have reviewed…"

David C. Poland replied to Lars Edwards's discussion New to Group - All Wave 12
"Hi Lars -   Your Napier cabinet should have the "auxiliary antenna tuner" mounted on the right side of the cabinet.  Have you reviewed the antenna info in the owners Instruction Booklet? On your work bench, use a long wire…"
