I think Samson is Sam Ash.Hartke is owned by Samson. Even if they were owned by Sam Ash, their closest store to me is a thousand miles away in LA.
I'd give them a call. Maybe they can issue a call tag and fix it.
How long have you had it?

Sorry, I might have missed some posts.Right, as previously noted earlier in the thread, but closest store is 1K miles away.
I bought it used a few years ago. I got my money's worth, and don't want to throw any more good money at a heavy amp I'm not inclined to haul around anymore. Looks like I have a taker for it, so it's all good!![]()
what makes you think I haven't tried that alreadyOpen it up and start poking around.
Everybody just calm down. See the smiley winky face?

what are you going to replace it with?Welp, the ayes have it and the amp has found a new home. That's the last of my heavy bass rig gear, so it's a milestone for me. Hoping it finds new life and continues to support the music makers.![]()
what are you going to replace it with?
That is a very reliable amp... It's probably just something simple. My LH500 was my main gigging amp but once I bought a Mesa WD800 the LH500 is my backup.
So, pray tell, what was the bench fee to investigate and then fix? And who is your tech? I am sure a few local members would like another goto tech.OP is happy to have lighter/minimal gear, the amp stays out of the landfill and has a new home. I am happy to be the lucky recipient and to have fixed it. The culprit was a failed NTC Thermistor on the ground leg of the AC going to the power switch. Hartke used NTC thermistor to smooth the current spike at power up. Not sure what caused it but it is behaving nicely with a new thermistor. I think this amp sounds fantastic and it pairs very well with my fretless. I enjoyed chatting with Esteban when I picked up the amp. Very nice person and TB'er.

I am my tech. No bench fee. I only tech for me.So, pray tell, what was the bench fee to investigate and then fix? And who is your tech? I am sure a few local members would like another goto tech.
Ha ha if I'd paid the $100 bench fee and they told me it needed a "thermistor" I'd think they were making it up.OP is happy to have lighter/minimal gear, the amp stays out of the landfill and has a new home.
