Well, I'm down to 3 unfinished projects that have been in the queue since last year.
Finally got a JVC 4VR-5456 fix/restore completed to move back onto a Pioneer SX-100TA and SX-1000TA thatbhave been sitting open for way too long.
Here's a little tidbit of info on the JVC - the amp boards are not swappable left to right and never trust what a previous owner may have done. It worked poorly in 2CH but put 21V on spkr terminals in 4CH mode.

yep i have all of that, going to start checking voltage in the outputs but after that im kinda winging it. i thought about doing a rebuild as my GF is a electronics tech but hasnt worked on stereos much, i know i need to fix the R1 & R12 resistors as they are cooking the board.
Let's see -
1) Fix the McIntosh tweeter tower on my XRT 20's. Have had the replacement tweeters going on 6 months or more.
2) Build open baffle for those Wild Burro Betsy's I bought on a whim.
3) Set up a permanent place for washing vinyl, instead of the back-destroying, sit-in-the-floor ad hoc madness that is my current arrangement.
4) Build those 1 sheet of plywood vinyl crates.
5) Find another Altec Lansing VOTT A4 in a different barn (as if, lol).
There are about a dozen more that are firmly in the "only in my dreams" camp, as well.

A common solution to these hot running resistors is to install wires and locate a high wattage resistor remotely on the chassis to act as a heat sink.

ive got the resistor to replace the stock ones, do i elimite one one or are both replaced with the one mounted to the heat sink?
Remove the original ones, solder in two conductors, and route them to the remotely mounted equivalent. Pictures above are an example.
okay thank you, had to blow the pic up to see. thank you sir for your help
A couple years ago I ran through, checked and recapped my Revox G36. On literally the second to last screw to reassemble the machine I broke the FF switch and maybe another one or two. Stared into that fragile mess of now effed up switch parts, sighed, and put it into the storage unit downstairs, along with all the parts that I had gathered together for the case I was about to have built for it. Had even just put in a nice new unobtanium tape counter in it, they are completely impossible to find.
Still down there in the dark lol, lovely machine, dunno if I have the heart for that bisection disassembly again to do battle with the 70 year old switches...
Maybe one day?

Assuming wooden posts maybe saw them off and burn the stumps out or hire a breaker.

The posts are already broken off anyway. Need to remove the 'big' mounting concrete in the ground which the wood posts were mounted in to install new posts in concrete. My thinking is I have to hire a fence company who has a team of guys to tackle the issue. I've done two posts before, at different times, NOT EASY, but not 6 or 7 at one time, and fix the fence. A NIGHTMARE job for one guy - many days. Then got to jury-rig the fence back together. Too Many Hurricanes.
Who is a Breaker??
Thanks for your reply!!

Ah yeah my sympathies, been there, I wish you luck a lot depends on how strong the concrete is usually it's far stronger than necessary. A breaker is an overgrown electric hammer drill, a jack hammer they come in various weights. Like everything having the right tools can make it a lot easier.
Or leave the concrete in the ground and sink new posts in between.

That is a nice looking machine! I love the lighted round dials and lighting around the heads. Tape machines are something I'll never work on again.
I've found them to be more frustrating to work on than any other piece of equipment. Especially the overly complicated for no reason tape machines.
The last tape machines I worked on were Marantz 5020 and 5220 cassette decks. I only bought them because I still had a lot of cassette tapes and I really liked how they looked. After restoring them I wound up keeping the 5020. I thought it sounded better than the 5220. My son has the 5020 now and it still works fine except for the auto stop. But I refuse to open the thing up again.
Both were a PITA to work on. I still have a couple cassette decks that were given to me. A dual Tascam that was brand new, and an old Technics dual deck from a rack system that still works perfectly without any work done to it.
If it weren't for me still having taoes I wouldn't own one.
I had a RTR, but pre-recorded tapes were expensive compared to vinyl records.
I do think RTR's are the better machine, and can sound better than an LP record when music is recorded at the highest speed.

Two Settons: my RS-440 receiver and a recent acquisition, a BS-5500 power amp. Both need more service than I can give them, they really need to go to a tech, but I don't have the money to blow on that at the moment. But the Settons are just too damn pretty to get rid of. And before it started getting interference in the phono section, the RS-40 was my favorite receiver.
I've got two Philips turntables that need servicing, but those I can do if I can just get of my lazy butt and get to it.

Yes, I've rented jack hammers from Home Depot for fence posts before - not fun. Also ground out the wood in the existing concrete - also not fun. 6 posts? Guess I will just 'bite the bullet' and get a fence company in here. Too old for this sht.
Well for me i have a Yamaha M-2 that i bought in non-op condition in 2009, that was to go on the bench last February. But my brothers-in-law Sansui rack system he brought back from Korea in 86' is sitting on the bench instead (not working). I'm going thru the whole thing except the cassette deck as a retirement gift. He doesn't know about it because his sister snuck it home for me to repair it. We overheard him talking about looking for a repair shop when he had the time & that's all she wrote. But the unit i really want to get to is my dead Pioneer A-27 in my avatar, had since 2010. It's in line right after the M-2.
