Raytheon porthole M1105 mousehouse

[Bill Cahill]

I had a neat Airline with a good tube, and, a chassis full of rust. I rebuilt it, then tried it on my variac. At about half way I heard the vertical. Then, a snap, and, B plus crashed, went to negative, and, at 225 - volts, I gave up. I found out flyback was shorted. I had heard an arcing sound when voltage suddenly crashed.... There was a boost cap of10 mf 350 volts. It kept going negative. A lot of checking, and, no good Then, rusty strap on picture tube broke, tube slid out, and, POW. Neck broke off, and, rest of tube broke on the floor. I gave up, stripped it, and, junked the set.
I have the same model as your M-105, now. It intermittently played, then went to a raster
The rubber AGC wire going to flyback was rotted, and, shorted. After a long time, I found a wire. But, wiring on agc circuit is qu9te different....

Dang those varmints! But a nice save. And thanks for reminding me I need to resume work on my own 1104 . It's only coming up on 2 years since I started it.

BTW I really think you should have restuffed the varmint gnawed capacitors.

Sorry for neglecting the thread. I've been busy ...

I just got my 17" 10L43 predicta back together, it only took a recap and fixing someone's butcher job on the CRT/speaker harnesses.

(except for what they ate)! Do yours have the inductor tuned tuner? I had to drench mine in WD40 to make it move. Mine has high voltage, no vertical (open eaten yoke).
Lots of rust! Filthy when I picked it up on the street! Good CRT!

Why mice love them: Un-screened hole on bottom of cabinet for easy under chassis entry, back does not cover convenient access path on either side of the chassis...If they don't have to chew their way in, and a cat (or other predator) can't fit in then there may as well be a sign "mouse community center" on any dormant set in an environment that has mice.
Yeah inductive tuner in mine. It moved fine, but needed a LOT of help to switch between low and high band till I lubed the band switch...It still is a bit sticky, but so much better than it was.

That would be like putting Rosie O'Donnell in a thong...Waay too little hidden.

Before I pulled the chassis I was considering a restuff. I was imagining a clean original chassis with all original caps and when I found a rusty mouse mess with mid 50's molded plastic replacement caps and replacement tubular lytics with 3X the needed lead length used on crude installation...Seeing that I decided, screw it, it is neither practical nor possible to restuff this mess...Except maybe the chassis getting restuffed back into the cabinet with no resto for disposal...I'm glad(ish) that I abandoned both restuff ideas.

The non-applicable 5 knob pencil box version is on the ETF (sam's 94-8)http://www.earlytelevision.org/pdf/R...-sams-94-8.pdf

The close (but apparently not correct) version I used during the resto is sam's 161-10 (click pictures then click them again for full size).


Tonight while sorting the ~1.2 decades long sam's library I recently bought I noticed there is a correct folder for my set: Sam's 141-11 (figures I find it 2 days AFTER the resto is done ).


It appears they made sets for other brands as well. This Coronado in Sam's 145-5 (which I have a duplicate copy of) seems to have the same chassis as my Raytheon.

Made by Belmont whom sold that chassis (and variants) to everyone and their brother, well into mid 50's.

You're not the only one ...A friend contacted me after the swap meet I got it at sayin someone they know collects Raytheon and wanted it $200 bad sight unseen....I did not want to sell it and later I was told they would pay $300 for it (at the time a working one on d'bay was $325). After the offers when I opened it to find the mouse damage, I nearly dropped the resto to sell it. If the one on the bay is still there and ya got money burning a hole in your pocket, then why not?.

Yeah, I think I saw a Silvertone, and another rebadge of it in Sam's.
