Is there a replacement for a IN60 Diode? Rat Shack only had IN4004. I will have to make a run to the parts store tomorrow.

6AG5 RF AMP

6AU6 2ND VIF
6AU6 3RD VIF
6AU6 SOUND IF
6T8 DET/AF AMP

6AU6 VID AMP
6AU6 DC REST/SYNC LIM
6SN7 V OSC/V AMP
6W4 DAMPER
1B3 HV RECT
6BG6 H OSC/H OUT
5U4 RECT

PLUS A 12LP4 CRT

The set work OK for the gutless wonder that it is.

Doesn't seem too gutless to me....looks like the only features missing are a seperate horizontal oscillator tube and an agc keying stage (which may not have been in other sets of its age anyway).

Chad,
Your point is well taken. But you must admit, 15 tubes (plus CRT), is near the lower limit of cheap design, though by no means a record. A Motorola VT71 uses on 15 tubes, though it was much more common for late 40's vintage sets to 20+ tubes to do the job. I was a bit surprised when reviewing my Muntz tube lineup to see 3 video if tubes. Would have expected 2 (or less).

But I looked at a Muntz set from a mid 1950s Riders, and it STILL had 16 tubes. So maybe the Muntz reputation for cheapness is overstated...?

So.... what TV from the 1950s-60s used the LEAST number of tubes to do the job? (NOT including compactron tube sets). BTW, I don't know the answer.

Many of Muntz's sets had only two IF stages. Also, he used many fewer bypass capacitors, filters, etc. His total parts count was much lower than the major companies.

The RCA 8" portable set from the 50's uses I think only 12 tubes (not compactron) plus CRT. It has a power transformer with selenium diodes...uses a lot of 6U8's...it even uses the triode portion of a 6U8 as an audio output stage.

I have a RCA 14" portable from the 50s (see avatar) that only uses 13 tubes (no compactrons)

I was looking through a 1958 Montgomery Ward catalog and they listed a 21" console with 14 tubes including the picture tube, one diode and 2 selenium rectifiers.

These 9" GE's use 10 tubes not counting the CRT.
If you are lucky enough to find one with a good CRT it can work really well.

Hey there!! Interesting find. I found this thread searching for Muntz and TV, because I happen to have a fair-good condition, working Muntz projection TV that I would like to sell. I have to confess, I haven't done the research on it yet, so I don't have a clue how collectable it is, or it's value.

It has a tweaked 13" Sony Trinitron (man, those things were great) sitting face-up, with a box on top, that contains a mirror, to a lense that shoots onto another mirror, then the screen.

I purchased it new, about 30 years ago. It is in working order, although I haven't used it for about 20 years. It was serviced just once.

If you or anyone else knows of where/how I could research this, or, is interested in it, please feel free to contact me ([email protected]). I'm in Los Angeles.

Muntz
 
Hi, guys. Nice, clean chassis. Anybody have a Muntz they're willing to get rid of to me? Looking for a table model set, or, two, or three. Have 0. Nice bit of looney, true information. On his most popular tv commercial of the 50's, they had a upright rect. Muntz tv sitting on the stage. The old man himself would come running out in a straight jacket, with two "attendants" chasing him. He stopped, looked at the large price tag on tv, and exclamed, "Why, my tvs are so cheap I Must be mad!". :banana: :banana: :banana: :lmao:

There was an article recently in Autoweek magazine regarding the Muntz Jet, the car Madman built in the early 50s. Not a bad car, really. Anyhow, it's demise was met when the accountants discovered that old Earl was selling the car for $1000 less than his cost to build it-so he really lived up to his commercials!
