tough213: Hello Retrochad I was wondering how much power a tube amp can handle a t full volue before it becomes distorted .I want to purchase a fixer amp with tubes but want to get some ideas what I need to look for in the way of quality .I have a solid state amp but I really enjoy the tube sound better thank you for your time and all the best keep up the great work
retrochad: @craig1974 You are right...it is not original. The switch broke on the original changer and SouthJK substituted in a later model changer.
craig1974: That changer does not look to be the original, and looks like its from the solid state era.
Patrick Saxon: Magnavox also made electronic organs too! I would fear of any electronic instrument in a barn as small animals could get inside and damage the circuits inside. I bought a late model Wurlitzter Total Tone deluxe spinet and a small animal urinated on the circuit boards, corroding it as the organ must had been in a barn.
moscowandy: I wonder what was that song name playing? ))
nice record player !
retrochad: This Magnavox was one a friend and I were working on and he let me have it.
puupydoger: Hi Retrochad I like some of your organ like keyboards and I have seen other people on youtube have this same Magnavox record player.
I'd like to know where you got this record player thank you!
Vinylrecordsneverdie: on here restored!
Vinylrecordsneverdie: Mines is on the way
Vinylrecordsneverdie: You're right, the can is grounded to the power supply.
Beside the filter and the tubes, some of the other component was replaced in the past like one of the audio transformers, a paper cap, and the power resistor. The paper cap was replaced with a Sprague orange drop. Therefore, I'm not changing that out since those rarely go bad.
retrochad: I would probably not connect the negative leads to the can of the old cap but make those connections on a terminal strip along with the wiring which connected to the old can (do not connect these terminals to the chassis ground) That way the old filter cap can will not remain "hot" with a direct power line connection.
retrochad: Yes they are...7025 is a low-noise version of the 12AX7 but they are otherwise the same. Best of luck on the repairs!
Vinylrecordsneverdie: According to tube layout on my set, the 2 audio amp tube are 7025. However, the ones on the amp appears to have replaced with 12AX7s. Are those a direct replacement for 7025s?
Oh yeah, I'm current working on the amp. Hopefully, I'll have the unit up and running soon.
Vinylrecordsneverdie: I notice the filter in mines is not original, but like you said I should recap it. When I install the new ones, i'm going to reuse the ground connections on the can. The changer is going to be a tough one, but however I should suceed since I took apart 2 Micromatic changers and turned to be a sucess story.
retrochad: When I did this, I actually re-used an old electrolytic can cap which was still working and insulated it with electrical tape (I think the can is "hot")....however this was a long time ago and I would really recommend using all new capacitors...sometimes you can spread the locations of the caps out around the chassis to save room. Also the new ones are pretty small...just dont allow the can to contact the chassis as the "hot" common neutral from the power supply is isolated from the chassis.
Vinylrecordsneverdie: When replacing the filter cap on this one, did you replace the can or install 3 caps inside the chassis mounted on a terminal strips? I have plans on restoring mines pretty soon and that chassis looks pretty small too mount caps inside the chassis, but I'll figure out a way to get 'em in there. Can caps are sure hard to find.
ChromeBumpers: very cool, five *****'s
as we've heard over and over, "they don't build 'em like that anymore!"
damusician: that same console is one ebay right now, but it has a mid to late 1960's vm changer in it and newer e-caps.
kyletae: This is the best. I have a mangavox phonograph that is from the 1960's I believe. I'm having troubles keeping it in actual motion. It keeps dying on me and slowly spinning to a stop. Any suggestions?
vinylman86: retrochad, does the isolation transformer keeps the unit from buzzing like if there's nothing hooked to the input jack?
