Cute maggie console all tube B&W mid 60's
got this yesterday, lite wood, 12" bass with a oval mid and small round tweet. SE 6bq5 micromatic changer, 23" B&W tube. Condition ok, a littel water damage in a couple of spots, not bad.
I like the size, smallish with the round legs with brass boots. this will be the 3rd of this chassis, so I know it pretty well now and what to expect. I will get some pics as soon as I find the camera. What I really like about these old console sets is how you can drive the stereo amp directly off the converter or DV player and get good stereo sound. The speakers are pretty good in these old maggies, beat the daylights out of those little ovals most of the box cabinets come with.

wow you got another one! I seem to attract zenith combos. There was one of these locally but the gal wanted $150 for it in not working condition. I just couldnt pay that much for a bw.
How do the crts seem to hold up in these? All the 21 inch bw sets I have found have almost dead crts. They dont seem to last like the smaller ones. I have all my combos setup like that. I usually just put a bypass on the tv power switch so i can leave the tv in the off mode which connects the amp to the speakers. Most of the combos sound really good with a clean input. Hows the flyback meltage in this one?

fly looks very good, so far CRT's have been ok to weak, but all work.
power tranny looks/smells ok. Both EL84's are shot, as is to be expected. I did not remember seeing a rectifier tube, so I am guessing a doubler circuit. those IIRC have the under the chassis caps which dont seem to hold up as well as the twist locks. There is some water damage to the particle board bottom left front, I will knock it down and stablize with some epoxy wood filler. I would just cut it out, but its what the wiring diagram is glued to, and I would like to save that. The size is very nice, should fit into a small room very well. I think I could set up a small flat screen color (boo,hiss) on top for watching color shows, and use the B&W for vintage programing, both using the stereo amp of course. I will pull the HOT and do a current monitored slow power up just to see what happens. there are a couple suspect caps in the HV circuit that are 50/50 (white tube shaped) I prob should pull the chassis and check for bumble bees or black beauties, as this may be a 60,61 which may have used those instead of the white tubes like the others. This was a 20$ deal so I had to go for it. With the DVD/converter you get the full remote experience which is very nice, Just need to get a clapper to turn it on and of and I will be good to to. I considered the use of the aux, but it was a real easy fix on the last one to just add in another RCA input, clip the wires on the waffer switch, and run the new RCA to the remaing channel, now clipped off. That keeps the TV power on switch working AND saves the aux for a CD player.

I have never been a fan of having the woofers setup like that. To much cancellation. I have an rca like that and an one where they both fire front, everything else is the same and the front firing had 5x the bass.
I cant get into any of the old shows. To me its like watching a foreign language movie and dont understand a thing. I sometimes watch the news on my bw if I stand the propaganda at the time. I have noticed that the filter caps will act shorted and get hot then if you let them cool down they are fine. Its like something breaks loose and they un short.

That's a nice Maggie. I'm diggin the simple "modern" look of the cabinet. Looks like it has the same chassis as mine... I think they used that chassis for several years. I don't think mine has any tubular caps... they're all early generation orange drops and also the brown drops (if you wanna call them that). Mine was playing fine till a filter went south and started leaking AC into the picture.
The CRT in mine tests excellent. The lady that had it previously said they didn't watch TV much... they listened to the stereo mostly. That might explain why the CRT is good and the stereo outputs are bad.

well I hope to get to it soon, but I have to make room. Yea the looks really got me hooked, simple clean, and those brass boots are sweet.
I dont need to fix the stereo amp to check out the TV, so that will be looked at 1st, no hurry on the amp/tuner.

The one you recently had with the "hula" issue... that was a maggie, too, right? And you had another as well... prolly same chassis again I bet. Any more of these sets, and you'll be able to get certified by Magnavox!

low b+, turned out to be both the doublers were open, I tacked on a couple, ane replaced some of the ceramic tube 1kv caps (.1, .047, and .001) just because. the .001 was leaky the other were ok.
fired it up, no HV, replaced the HOT,damper,rec, got HV but a odd looking raster, looks like the vert is barely working and the Horz was not full. checked the vert tubes, the vert osc has a high grid voltage bias should be -40 but is more like -8. the plate was way low, but that is prob due to the goofed up bias on the tube. there is a .0051 5% coupling cap that may be leaking (the other side has 250v) so I will replace that with a .0047 (all I have) if it is. if that is the problem then I will order the right part later. I checked the VOT it may need a bypass cap, its not shorted so I jumped on on, no help. So I think its that vert osc. Tomorrow I will check if that is not it then I will break out the scope. I checked the plate load resistor, ok as is the vert height pot. The -8 means its trying to osc so hopefully that will be the problem.

I have a Magnavox vertical output transformer that came out of a '60 model 23" B&W console. It has 3 wires and the P/N is 320254-4. You can have it if you think it will work.
