Sir Janitor Tzap . . . . . . .
( and frankly . . . . I think that YOU are noteworthy of more muuuuuuultiple T's Z's or A's . . .all being in accordance to how long the electrical arc is ! )
How long has it been . . . . .well long enough that I totally forgot my Four-rum password . . . . and then had to crawl in thru a rear window.
If that is the bottom chassis of that radio of the mans . . .and not another copied photo . . . .that is being one CLEAN chassis for its vintage
of circa 1956.
Considering that he can handle the units outwardly appearance aesthetics . . .the radio chassis should be an easy fix.
What I am a seein':
That is being a PREMIUM chassis for that time era with it including a frontal RF amplifier stage, provisions for phono input, a tone control and having
a bit larger speaker . . .cone and magnet . . . . than was then the norm.
( However, its showing a powdery cadmium oxide coating . . .and its shedding. . . . .cosmetically . . . . . . just like some of my OLD machine screws and nuts)
If you had the tube filaments all lighting up, I feel that its only need is that open primary audio output transformer being replaced.
The volume control cleaned , the large canned filter replaced with new tubular units IF it is presently causing any 120~ humming.
The one capacitor that is inherently bad is the coupling capacitor between the plate of the 6AV6 and the 6V6, which just happens
to have used a trouble free disc ceramic in this situation.
What you are basically now wanting is an output transformer installed . . .at no cost . . . to evaluate the set.
That is possible if you go thru all of your wall warts and find one of a 5, 6 or 9VAC output.
( In my area I can buy one of those for a buck a pop at thrift stores / flea markets.)
(Be sure that it is not a 95-240VAC input switchmode unit, which would all be DC output)
(If only finding transformered DC output models, that will involve getting in the case for AC winding access and diode /capacitor disconnects. )
The blades of the wall wart go to clip leads connected to the screen and plate of the 6V6, while its AC secondary feeds to the speaker, after one
lead of the old output transformer secondary is lifted.
I fully believe that you will then have a talking radio for evaluation purposes.
I know, and can tell you of several of that needed transformer, now available in the realistic $4-6-8 range.
It is a nominal 5K primary to 4 ohm secondary impedance.
If you mismatch in using a slightly higher impedance . . . . its effect . . . the overall bass response will increase.
If you mismatch in using a slightly lower impedance . . . . its effect . . . the overall treble response will increase.
Sooooooooo . . . if you want to get in contact with that owner for repricing again, there won't need to be
anothers outrageous transformer scalping involved.
( Reminds me of E-bay where some ( multiple string of 12 diminutizing cursewords ) person had multi-paged ALL
of his small COMPONENTS
unit prices of either $9.95 - - - - - -$19.95 - - - - - -$29.95 . . . . . . .with FREE shipping.)
Thaassssit . . .
FIO . . . .
The schemas abraded portion of the value of the plate load resistor of the 6AV6 is 270K and they have a 4.7 meg resistor used for its 1st grid
vice the ?18? listed on the sheet, with a 10 meg being another viable value, if being operated on up in its starved plate current mode.
