    Took a little detour from the usual motorcycle work over the last week to upgrade the shop's audio system.
    If you're going to work on 70's bikes then it's best to listen to 70's music on a vintage audio system, right?
    A vintage Fisher receiver is getting replaced by a nice Sansui that my brother-in-law gave me.
    While the Fisher is nice, the Sansui is really nice and packs a few more watts as well.

    It's seen very little use over the last few decades and will get some maintenance before returning to service.

    This receiver was built in 1979 so it's chock full of 40 year old electrolytic capacitors. Don't want to bore any of you that aren't into electronics but what that means is they all really need to be replaced as they dry out and go bad with age. Running this unit with the old caps in place is just a ticking count down to letting the smoke out.:photog
    Ordered all new electrolytics plus a few other parts so it's time to jump in and get them all changed out. At least this old stuff is repairable.

    Several hours work, piece by piece, board by board, and the surgery is successful. All the lamps for the face were burnt out so they got upgraded to LEDs.

    Had to re-do some shelving to make room for this beast.

    that sucker's a beauty, and worth some money to vintage audio guys. You definitely owe one to your brother-in-law.

    I had one of those! Never could have afforded one, but a monetarily enhanced friend had one that he was going to throw away because it quit working. So he gave it to me. All that was wrong was a blown fuse.

    I traded a 350 Honda engine to another guy for a set of Radio Shack Optimus one speakers. Pink Floyd at maximum volume.

    Quick, name something that Fast Idle doesn't know anything about or can't fix....



















    yeah, that's what I thought. If there is ever an apocalypse, I want Fast Idle in my bunker...

    Yes, I do. I'm really happy to have it.
    He wasn't using it and knew it was going to a good home.

    Those were some good days back then!
    Luckily I still have some vintage speakers for it. Seems speakers always stuck around longer than the electronics. Too bad so many amps and receivers went to the landfills.
    The new digital stuff just doesn't sound the same.

    Years ago I bought a new Sony system. After a while the amplifier start making a buzzing sound. Took it in for repair and found out that the board was based on one chip with "large scale integration". The replacement lasted just long enough to get past the warranty. About that time radio stations stopped having oldies music shows, and I haven't listened to radio since then. Thank goodness for the internet. I can still find 1950s music to complement my boxes of 45 rpm records.

    Thanks Man...Stock 3 on the tree shifter gave up the ghost so a ridding bud sold the Hurst shifter to me...low hours...from the 70's not used since...said it was in a pick up...
    Don't think so after having to extend the shifter 6 inches. No big deal because I had to mod it to work in my van...Had to spin the shifter 180 degree.
    My hot rodded Ford Van...Inline 300ci Six, Clifford Manifold with a Holley 390 Four Barrel with big K&N cleaner, FI exhaust headers with Y pipe to SST muffler dumped before the rear tire.
    GM hot HIE sp? ignition.
    Honks like a raging bull.

    Funny that you post the electrolytic info, I was just given an old bose acostimass not working with the cubes in fair but not working condition.

    This is what happens when they pop... 20190618_103423.jpg

    I like the pulley system that moves the station dial back and forth on post #1061, second photo.

    Still use my JVC amp from the early 70's...used it this afternoon.

    We pulled a old tube radio out of a abandoned 1940's car we found back in a wood lot as kids.

    Took it home and hooked it up to a battery and speaker.

    I remember how strange it was when it played music of that present time, instead of the 1940's.

    Kids......

    A great home, where it has already been renovated before being put to good use!

    Can we all share a bunker come the apocalypse???

    I've got a pair of old Sansui 3 way speakers that I rebuilt about 15 yrs ago that still sound sweet.

    I remember a soft glow from the radio dial while waiting for tubes to warm up. There was always a gentle background hum that gave the old radios "character".

    My Nanna had an old radiogram, 78speed player, an CRT electronic eye. I should have been dead crawling around the back of that thing as an eight year old without discharging tubes etc.
    Some cool old records, and memories :-)
