GK112 combo amp speaker replacement?

[jimmack]

Hi TB community. I have an old GK112 combo amp with what I'm assuming is a blown speaker. I haven't used it in forever, but I'm playing again and will need more than just my 25 watt practice amp. I recently plugged in and the speaker sounds crunchy when I play low E and low B strings, but it sounds ok with the higher strings. Blown speaker? If so, is it worth replacing, and if so, any recommendations for a repair shop in the Atlanta area?

Also, I do have an old Streamliner 900 amp, but sold my pair of 210 cabs long ago. Instead of repairing the GK112, would it make more sense getting a lightweight 10" or 12" cab and just go with that? I don't imagine playing anything more than bar gigs so I don't need a big rig (at least I don't think so...). But I'm thinking the Streamliner with a modern speaker might give me some good flexibility for different needs.

I know these might be questions of personal taste, etc., but just looking for some opinions.

Thanks.

I have one of the 700RB/112 combos. It's easy to disconnect the internal speaker and hook up an extension cab.

Before replacing the internal driver, I suggest testing the amp with another cab.

I would also pull the driver to make sure the problem is not a wire or some foreign object hitting the back of the cone.

If the driver is blown, I would contact GK to see if they stock a replacement driver or have a recommendation.

If no, then you need to figure out the internal volume of the cab and measure the port dimensions, so candidate drivers can be modeled in the cab design. Some TB members will probably volunteer to do the modeling for you.

I would want to be sure the driver is the problem BEFORE replacing it... I doubt that it's the problem. Don't connect any other amp to the external speaker out jack, the GK amp MUST be disconnected from the speaker before testing or you could damage the other amp (even if the GK amp is turned off).

If the driver is bad, contact GK for a proper replacement.
