Got this for the price of a 1/2 tank of gas (free tv, I just had to pick it up).

If the chassis is as nice as the cabinet it should be a breeze to get going again.

You can't see the top, but the finish is mint.

Nice set! You'll probably be home free if the flyback and CRT are good.

I will have to put this one on the back burner, still have to finish up the big console (refinishing that is), and find a proper home inside the house, then I have the other maggie stereo console I got a week ago to work on (all tube, 6bq5 pp micromatic TT) also in need of a refinish, and a home inside.

My poor car is having to deal with a florida summer out side for the 1st time in 17 yrs.

yikes, looked at the flyback, not pretty.
Hopefully it still works, but if not anybody know fo a vendor that has old flybacks?

crt was weak but rejuvenated ok, cut of is just ok.

B+ is shorted causing the CB to break. next up is the fiter caps for a quick leak test at rate voltage...

i have a bunch od merit flybacks . If you can cross the original part number to a merit i will check if i have it

I found one from moyer electronics, if for some reason that does not work out I will get then numbers to you, thanks.

My new problem may be the PT, I think there is a short in the secondary HV to ground causing the B+ to short out, got some more checking to do (I need to disconnect the PT secondary to be sure, but seems to be the case).

good news just some leaking filter caps and doubler cap. will restuff and continue. Got the new flyback today, very nice NOS, I hope I dont have to use it but good to have in case I do. Should be getting the B+ fixed by next week (have to order the caps). Bunch of bad tubes, 1 in the tuner, 3 in the IF strip, one in the audio board, and one on the on the vert board. Yikes, this thing needed more than 50% new tubes.

alright now!!

replaced both doublers, restuffed one of the cans (will do the other later), works GREAT!!!

that old beat up flyback works fine, but at least I have an old one JIC...

Pics later. I still need to restuff the remaining can cap for relialbitiy, but other than that this one is fine. The CRT looks nice too, bright with good contrast.

as a precaution, I measured the cathode current on the horz output tube, it was right on the money per the schematic, so even though the flyback looks like it belongs in the garbarge, it seems to be working ok. I will leave it alone.

That set sure has a pretty cabinet. Someone took good care of it. Very simple cabinet, but in this case, less is more! Does the automatic brightness sensor work well on it?

DaveWM · #12 08-12-2009, 07:00 AM

the cabinet is nearly Mint which was my motivation for getting it (that and the fact that the guy said he would give it to me, he was glad to hear that it would not be junked, but rather fixed and used, he like me appreciated old stuff).

Yes the auto bright adj works very well indeed.

The simple cabinet it timeless, very classy looking. The only problem it has is the tuner knob is kinda loose, not sure what is going on there. I don't think it is the tuner itself, just the knob.

oh one other thing it has a audio tone control, very nice.

Does the knob use one of those little flat tabs inserted in the hole? If the little tab is missing, it won't fit snug at all. If you have a box of knobs, you can likely pull from from Paul to pay Peter.

I will check and see, thanks for the suggestion.

almost done, got the remainging caps from mouser, so will be stuffing the remainging can and replacing one axial lead cap, also need to replace a couple out of spec power resistors. Mainly was waiting on the caps.

Hope to move this one out of the garge soon, my car wants back in
