Thanks for your video, I just acquired a Magnavox amp converted for hifi like yours. It has 6v6 and 3 preamp tube like yours but no choke and a smaller rectifier. I'm wanting to go thru it but not sure of the model number for schematic.
Thanks for the vid. I have a 1060s Zenith console with turntable and AM/FM tuner. The turntable is not original. They replaced the original with a 1970s BSR McDonald. I managed to restore the turntable but like you mentioned in the video it has that grinding noise and then switch stopped working and the table won’t use stop. The tuner then gave me trouble and the AM stopped working. FM was never receiving well. Now both just lots of static. Overall I am considering updated it to modern specs. But I do like the mono/stereo sound and it’s all nostalgic for me. Any advice or ideas about the tuner I would appreciate your thoughts. Thanks
Really looking forward to this series. As a newbee, I have been hesitant to dive into a full blown tube amp project. Over the summer I picked up a working Magnavox model 1ST263 console with a cute little 8608-01 single ended amplifier, which I pulled out but have not started to work on yet. I am full of questions. Is it possible/advisable to use the power switch from the tuner chassis? It is a combination power switch and treble control, I only want to use the power portion. Same question for the volume control. They might be too big for the tiny chassis. I think the big, old knobs might look nice. My chassis is pretty ratty, I am thinking of possibly stripping all the components off to refinish it. Is that a good Idea? How should I go about that? I want to ensure that I can put it all back together again. Components are riveted to the chassis, should I drill those out and re-fasten with bolts? Power cord, to ground or not to ground? I plan to add a vented bottom cover for safety. X/Y cap? There are a lot of little ceramic caps, should they be replaced? I have to go cheap, I am thinking about replacing some of the resistors with high quality, precision ones from a old Tektronics RM529 TV scope that I was gifted, bad idea? I will be using a fuse holder from that unit, and possibly the power switch with neon pilot lamp. I also have the pilot lamp and Magnavox badge from the console. Any thoughts on speakers for this tiny amp (1-2 watts per channel) ? Should I consider new output transformers for 8 ohm speakers? I could go on.....but I will save something for later. I hope these questions might help everyone. Thanks.
I too have questions regarding the tone/feedback circuit for , Magnavox 8601 circuit that I've already rebuilt on a new chassis. It looks like a real stereo from the 1960's now and sounds pretty good but still want to tweak it as it sounds a bit thin sometimes and think messing with the tone and feedback circuit could give it more magic. If I was you I would use a new alps pot for volume control and drilling out a new chassis only took me a few hours. I used all new parts except the transformers, if you must go cheap you could test the old resistors only replace the out of tolerance ones. You should be able to leave the ceramic caps as well but they are not the best for sound quality. As far as speakers just look for anything over at least 90db. Hope this helps.
Back in 2016 I worked at a county landfill as the gatehouse attendant. Someone dropped off one of those consoles, one day. I didn't have a truck so I unbolted all the electronics. I'm going to sift thru them right now
Hi Mark, I have been waiting for a video like this. I have a Magnavox 175-67 6v6gt Push Pull Stereo amplifier with 12ax7, what is a good source for the schematic on it? Thank you.
My dad had a custom built console made around 1964 with a 15 watt per channel Harman Kardon receiver, Garrard turntable w/Shure cartridge, and 2 12" University coaxial loudspeakers. I remember it sounding amazing. The receiver had a copper colored faceplate. Anybody have an idea what model that was?
The Harman Kardon Recital models have a copper colored face and case. I just bought one on ebay for 70$ lol. It's a mono 20 watt but has hookups for 2 speakers.
This is really lame , console amplifiers are limited in low end frequency range and usually are 7 to 15 watts at the max output, far under the minimum requirement of 25 watts to a max of 150 to drive modern speakers with an ideal range or 75 watts per channel. Console amps were designed to work with the more efficient speakers in the console. They have a more limited range in the low end as it would not be possible to have a high powered wide ranged amp with wide range speakers in a single cabinet without serious feedback from the turntable. Console manufactures knew this and designed them to operate with other components in a single cabinet. If you want an amplifier for hi fi stereo use then buy a vintage component amp or new one for that purpose, consoles should be used as they are.
