Hartke LH1000 passive input broke off

Discussion in 'Amps and Cabs [BG]' started by Subersibo, Jun 10, 2021.

  1. The passive input jack to my beloved lh1000 broke off when someone accidentally pushed the instrument plug down while it was plugged in. I used the active input but had to turn up when using a passive bass. No biggie but I do want this fixed.
    Brought it to the local amp repair shop but they couldn’t fix it. Tech said there is a special tool needed to access a screw in the amp. $60 down the drain.
    Anyone know any Hartke repair specialist in the sacramento area? FDB73DC9-5660-4E77-9ADA-4180109F2002.jpeg

    Ummm, special tool? I don't recall this to be the case. If they don;t have the tools to repair the amp properly, they shouldn't be charging for attempting to repair the amp? They should politely apologize for their lack of proper tools and return your amp without charging you anything. That's my opinion anyway.

    See who Hartke (Sampson Technologies) recommends.

  3. I'd be curious to know what that special fastener is.

    As a kid, I had a summer job working at Philips Electronics repairing appliances. The only special fasteners I recall were oddball security screws used on their coffee makers and other appliances, because they didn't want home handymen tinkering inside.
  4. Thanks for the link but nothing is showing up for 100 miles of my location.
  5. Kinda sucks that they ask for a $60 deposit which will be used for the first hour of working on the amp regardless of whether it gets fixed or not.
    I could live using just the active input but my ocd is bugging me to get that passive input fixed. Also, the feeling of plugging into passive and having the volume at 1 and rattling the walls just gives me a sense of power over my bandmates lol!

    If THEY don’t have the tools or knowledge to work in the amp, you shouldn’t have to pay to find this out. That’s on them IMO.

    PM me and I might have some options. PM me who was unsuccessful too, I need to know who in our area is struggling with such repairs.

    Those amps have the modular type inputs that solder directly to the board. If you had a replacement, it can be fixed. Now if it was the old Amphenol type you could easily replace one if you were handy with a soldering iron. If you cant find a tech to work on it and you are in an inventive mood, and you feel lucky, you could swap that out for the old type and solder the wires appropriately. Just sayin ;)

    Seriously, it takes some real chutzpah to tell someone "I couldn't get it apart" and then charge them a bench fee.

    As far as 'special fasteners' are concerned, any real shop has the tools, or is going to get them the first time they encounter this rare and exotic new fastener. What could it be anyway? Torx? Reed & Prince? The assertion sounds dubious to me. And so does the expertise of this shop...or at least this particular technician.

    I was going to make a tool reference, but it would have justifiably been removed by the mods.

    I'd go back, get your money back, and never darken that door again.

    Is the special tool a soldering iron?

  11. Well, I do hope they return my $60 to use at another repair shop but he did say he spent an hour on it already trying to figure out how to fix it but couldn’t coz of that special tool that would cost like $50 that he would only have to use once.
    And I thought it would be an easy repair.

  12. Aside from security screws, I think the most exotic fastener I have encountered was Bristol Spline on film projectors, But I've never seen these used on electronic assemblies. Torx is so common nowadays it's not even worth mentioning.
    Edit: Perhaps the special tool they were lacking was a 1/2" nut driver.

    To he honest, I hadn't considered some type of security screws -- and Hartke's just weird enough to do that. It doesn't change the fact that guy shouldn't charge the OP. I get that the guy had his time invested, but the OP shouldn't be liable for the cost of him gaining the knowledge that he couldn't fix that amp after all. That's BS, IMO.

    I had the compressor motor on my 'fridge burn out during the recent power catastrophe here. The tech who came to the house spent about a half-hour disassembling/reassembling the unit enough to diagnose it and inform me that it would be $1500 to get it fixed -- about what I had paid for it, so I opted to get a new one. I figured I'd be on the hook for a service call, but he said there'd be no charge since they couldn't repair it. I was pleasantly surprised -- and the guy wouldn't even take a cash gratuity; said they had a company policy against it. You can bet I'll call that company the next time I need a repair done that I can't handle myself. Side note: if I had known how difficult and costly it would be to actually get a new refrigerator, I probably would have opted for the repair. Hindsight, as always, is 20-20.

  14. That is a great form of advertising.

    I call BS. All online photos show standard Philips head screws used around the enclosure.

    Get your money back from the repair guy.

    I had a similar issue with an old Fender Pathfinder that I refurbished. If the input jack is soldered directly to the circuit board you can un-solder it and replace it with another in about 15 minutes.

    Tell me you did not take it to that guy on J Street in Sacramento...:meh:
  17. I did, Guitar Workshop at J St.
    Skips music was asking for a $100 deposit and a 6-10 wk wait time.
    Don’t know any other place, shoulda asked here first.

    This is not really relevant unless you can find photos of every screw that needs to be removed, even the internal ones. This is an input jack soldered to a PCB, so it is going to require a bit of disassembly. I doubt the OP will have much success getting his greenbacks refunded and will have to chalk it up to an expensive lesson in where to NOT take a repair. Dis'ing them on social media is an alternative that might one feel better. :D [Edit: I know some businesses will bend over backward to get you to amend a bad Yelp review]

    Seems to me like the tech himself is the 'special tool' in this particular case.

    This should be an extremely easy repair for any tech. I’d demand my money back for his incompetence. His lack of basic skills is not your problem.
