View Full Version : Gallien Krueger ML250 Replacement Speakers
11-02-2009, 06:17 PM
I only have tube amps these days but I still have a special place in my heart for the Gallien Krueger 250 ML (sorry for the heading typo) from the late 80's. I have a chance to pick one up used and know the speakers need replacement or a repair kit -- I prefer the later since the speakers have thier own distinctive tone.
Does any one know where to find replacement speakers for a GK ML250 or even better yet a repair kit for the foam suspension around the cone that has rotted over time?
The original speakers were made by Pyle, GK offers an Eminence replacement for $54.00 -- I just don't know which Eminence speaker it is.... The original pyle is a 6.5", 75W, 16ohm. Eminence offers the LA6 serie but they are 8ohm speakers.

I have had the original speakers re-coned in my 250ml a couple of times over the years,just recently replaced them with the Paragon/Eminence speakers from G/K. Cheaper than the re-cones and IMO,sound much better. They must be 16 ohms,or problems will occur ( over heating, thermal shutdown,damage)!

Replacement speakers from GK were cheap like $40 each at least they were a couple years ago. They had them in stock. That cab is a bear to open. If they are $54 now I'd still get them from GK.

Getting parts for the 250 is a pain! I dropped mine off at a shop about a year ago and gave up on it. I got the amp for $100 years ago and figured that it was cheaper to dump it than wait for parts. I would try replacing the speakers with non GK ones if you aren't willing to wait

The replacements are available on G/K's website,just checked,$54 each. The cab. is like peeling an onion to get inside, and not a lot of room to work in,but not impossible.

Anyone recommend a service/repair person/shop on these 250's?

Does anyone have a pdf or image breakdown on how to replace the 2 speakers in the steel box of the amp?
I ordered the speakers from GK and am awaiting their arrival but have no idea how to remove the top grill cover screws.
Anyone here know the dismantlement & replacement process?
I am emailed GK but never heard from them.

I replaced the speakers in my 250ml last year. Its not difficult at all. Take the sides and front screen off, then reach in with a 1/4 inch socket (If I remember correctly) and unscrew the mounting bolts. Be patient and careful when you install not to over tighten, its a bit of a challenge to reach in and get to the mounting screws in the center. Before you seal it all back up be sure to test the amp to make sure you put the speaker connectors on correctly. If you want to adjust the gain, compression and chorus remove the top panel, mark where it is factory set with a sharpie and then adjust to taste. The noise floor on mine increased dramatically with a corresponding increase in gain. Be careful if you decide to get into the top of the amp and adjust the settings, high voltage.

Thanks Vintage for your reply. Is there a way to quiet the amp, I noticed that when the gain is on it has a bit of signal noise there which as you know is not great for recording.
Have you ever used the amp with a cab? I made a basic cab many years ago and it was amazing, lost it but am interested in either building another unit or buying one. Just wondering if you have any suggestions. Store bought or custom built using off the shelf speakers? I am not sure what speakers I would even use. I am a blues/rock/funk player myself. So I want to stay away from the Van Halen crunch.
Thanks again for your reply!
