Mods and Updates

As of this notice, we will be suspending modifications and updates to used amplifiers. Don, the head of the mod dept., is retiring after 20 years of service.

Until we can hire and suitable candidate to head this dept. we will suspend all modifications and MK II updates.

We will still maintain our full warranty repair service as well as non-warranty/used repairs on older models.
