The Fine Things are Always Hand Made

Hi all, I'm new here, but an EH Scott admirer since I first learned of them, about 32 years ago. I finally acquired my first, and likely my only Scott radio, an Allwave 23, in a Warrington Cabinet. It's missing the color dial "window" only. I have the escutcheon, but would like to find a color window. Have any reproduction windows been made, or does any member have an extra one? Thanks in advance, I'd appreciate any help! Dave Pike

I made a dial window for my AW23. It had the original window when I got it (this style: https://www.radiodaze.com/scott-lens-early-5-knob/), but it was a shrinky dink. I ordered some colored overhead slides, cut little strips, and tiled them together with packing tape. Took me a couple tries to get the widths to match the print on the dial, but the end result was quite good.

Thanks, David! I remember reading about those caps, in some of the Information on this site, which has been so helpful, as well as advice from yourself, I appreciate it! I am low on my stock of caps, especially 0.047 @ 630 film caps. I will be ordering more soon, then will begin the tuner recapping process. I also will order the color dial window.

FYI - there is a Scott service bulletin concerning the many .1MFD  400 volt caps in the earlier AW-23 receivers, such as yours most likely. For any returned to for service, replace with .05 MFD 600 volts caps. Any other values, such as in the bass tone circuit, stick with original values. This was a running change for later production AW-23s. That is what I did to mine using the contemporary .047 MFD 630 volt film caps.

Hi Thom, Yes, thanks to this site, I've found and printed important info and operating instructions, schematics, service info, for my set. That blow up of the schematic is a great idea, you're fortunate! I have to work with a "spy glass" because my eyes aren't what they used to be! I'll be recapping and checking other parts in my tuner chassis, after I order more caps, and finish a couple other things first. Best wishes in your restoration progress!

HiDave:By now you have found the info on your radio. There are at least 2 schematics.I am fortunate to have a partner who is a graphic artist with a poster printer and have the 7 knob schematic blown up to 2 feet by 3 feet and framed. 
Since J 497 is a 5 knob version, I am putting it together. Following the early version schematic. I have replaced all the resistors and caps with what I find in the chassis, since some values are different from the schematic and parts list. In particular the screen resistors for the 3 IF tubes. The schematic calls for 1 K resistors, and the chassis has10K resistors. There is a 3meg resistor that feeds thru the chassis under the contact strip for the coil wheel. I am still tracing out some of the wiring, since most of the colors have faded out. You may also find that most of the rubber covered wire is crumbling. I found a source for it at bntechgo in a google search. Working on this chassis gives me great info for when I get brave enough to work on K480 which is a complete working radio. I

have completely disassembled J497 to clean the chassis and polish the chrome which turned out pretty well. Let the list know how yours turns out. Thom

Hi Thom, yes I have the 7 knob version, with one ANT. post. My serial number is
Q-487. Maybe someday I'll figure out how to add a couple chassis pictures, I'm still trying to learn how to navigate this site!

Dave: Thanks for accepting my request. May I ask what the serial number is? In 2011 I bought an Allwave 23 in the Waverly cabinet. Photos on this site. I had to have a new power transformer built by Heyboer transformer in GrandHaven. I did a recap while waiting for the transformer. It works well, but needs an alignment. About 6 years ago I bought a second Allwave 23 chassis. It has been ‘modified’ by a previous owner and is in rough shape. It sat under my bench until this this year when I started a complete rebuild and cleaned up 80 years of dirt. First one is K480 and a 5 knob single antenna post. Second one is J497 and is 5 knob with twin antenna posts. What interested me about yours is it is a 7 knob single antenna post.  Lots of variations in custom builds. Thom.

Be sure you read the owners instruction manual (available on this website) to learn about the controls to operate it for best performance and audio quality. 

Info Archive, select SET Folders, select ALLWAVE 23. 

Suggest you recap the receiver sooner, rather than later. That it plays suggests no serious problem, but don't tempt fate.

Thanks so much, David C. Poland for this very helpful information! I had forgotten to mention that my set is an early AW23, with 7 knobs and one antenna post. The original color window isn't in the cabinet anywhere, I checked that first, thinking maybe it fell down in between the front panel and shelf. My radio impresses me, since the tuner has it's original paper caps, which I will be replacing very soon, and still picks up SW extremely well, and is a little lacking in performance on the AM Broadcast band, but after recap and alignment touch up, I'd think it will improve. The PS-Amp chassis has been recapped. Amazingly, the little tuning meter is still working! Thanks again, I appreciate your time and help.

For the later 7 knob, frosted not clear. I got the part number correct.

The lamp projects dial strip graphics onto the escutcheon insert. Tuning meter tiny pointer also projects onto the dial insert.
