    Yup, it means if I ever do a replacement/upgrade outside using what they have now, I better make DARN SURE its a high efficiency driver lol....

    Why look!

    The rabbit hole is wide open now

    While everyone else was sleeping off their turkey in the house....

    I got to work testing this baby apart and labeling everything.

    Took me a few hours but I got it separated into Tuner | Amp | Preamp.

    The Tuner and Amp came out. The Preamp seems to be stuck so I’m not messing with it.

    Some pics of things...

    Still working through labeling and disconnecting everything:

    I plan to try harder to remove it tomorrow. I cant see if there are some sort of screws I'm missing......

    Amp as it came out of the console.

    "Wiped Down" section of the amp v original. Lots of dust and grime. Chassis is a nice copper color that I'd like to shine up if I can so any suggestions welcomed....

    Think this tube might have seen the last of its time

    Chassis cleaned up with all the tubes out.

    Anyone think this tube might have been a problem hehehe

    Looks like it gave up its vacuum :p

    I have a couple of questions for people.

    1. Any suggestions on how to clean up the chassis?
    2. Can I clean the tube sockets and if so with what and how
    3. From the underside, what are the parts I need to be replacing.

    Yup, thankfully I had a few spares that were in the chassis so I can replace it. I might also replace the other tube pictured as it just looks a little too "toasty" to me.

    Also my buddy is gonna loan me his variac to test the amp for any issues. I'm also gonna take it by his shop next week for him to give it a quick once over to look for issues.

    Deoxit on the tube sockets
    Tape off the tube sockets and try fritz metal cleaner.
    All i got

    Thanks. I will deoxit that.

    I'm debating how "nice" I want to upgrade things as well.

    There are a couple RCA connectors (phono and another set of RCA's) that look super old and corroded.

    Wondering if I want to use some BJC LC-1's to replace both sets, or something around that pricepoint.

    Ryan suggested Brasso for the chassis so I may try that first.

    I also need to clean the RCA jacks as well so I will be using the cool tool I got from @helipilotdoug years ago that was made for just this purpose.

    I'm also thinking about installing Y connectors for the phono as I "may" later on use a actual TT with this setup, but NOT the one thats hear already since it sucks. I'd connect the one there just so its connected, but install some RCA jacks on the back of the unit to hookup an external one.... but I think thats just me being silly on both counts......

    I will likely upgrade the FM RCA input, and also the input from the reverb unit since those functions will actually be used. The TT will likely just stay totally stock.

    Then I add in the chromecast that I got from Ryan to play audio........

    Looking good.

    Is your goal to use just the power amplifier or are you going to reconstitute the original console? Sorry I can't remember, and (at least at the moment!) I am too lazy to go back & look. :(

    The latter will be easier, of course.

    Plan is to get it back to totally working and in as good condition as I can. It’s got some wear and tear but the kind that shows character and it was actually USED.

    The TT will spin (but not be connected to the preamp). It will be cleaned up so it looks as close to new as possible.

    The Radio will work as normal, and the preamp will also function as normal. The only tweak is adding another input that will be used for a Streaming Device (at this point a chrome cast audio). Not sure how we will do that, potentially highjack the phono input on the preamp.

    The internal wiring will remain with the exception of the RCA cables which I will prob replace. I have a pair of MIT RCAs that may be used for the Radio to preamp connection, and then the preamp to reverb section.

    Maybe I will upgrade the bass driver if it’s worth it. Something more efficient or that has a bit linger throw... but that’s prob just going too far.

    Tons of pics incoming. Got it fully disassembled this morning and took a ton more pics.

    The pre-amp continued to fight me for a few hours this morning. I couldn't figure out why it wouldn't just lift out.... Finally went at it from a different perspective (removed the knobs) and realized it was screwed in from the top..... Then it all came out fast.

    All controls, RCA plugs, and tube sockets were given generous amounts of de-oxit because it will have months to dry lol....

    Everything taken out (except the TT)

    Most important thing is to label EVERYTHING! I think I went through a roll of labelmaker tape, but better do it now while its fresh than try to figure it out later. Every disconnected wire was labeled with where it connected to, and if it was going to the amp, from the amp, to the tuner, etc.

    I'm guessing that big can and then these brown tootsie roll things are what need to be replaced right?

    Its now all been put back into the chassis and will be taken out piece by piece and gone over.

    All the drivers appear to be in perfect shape, so its mainly checking the Pre-amp, Tuner and Amp for caps/resistors that need replaced, ensuring the tubes work (plan to have them all tested shortly), and then make sure the tuner alignment works.

    Potentially take the lamps and replace with LED's but thats a maybe.....

    Sounds like a good plan.
    I would change the aluminum (can) electrolytics (all of 'em); the film capacitors may well be OK. Tread lightly around the tuned circuits in the FM radio :p

    The cartridge is presumably ceramic, so the phono input can frankly be used as is for a line level input (although the loading should be adjusted a bit for best results).

    I ain’t touching none of it doc lol....

    I’m handling logistics of ordering the parts, and the light work and that’s about it lol...

    I’m not gonna try to learn on a piece this nice.

    I "think" this is the tuner schematic (found here)
