Tube prices gone mad……have forced us to raise prices immediately on any products using vacuum tubes. Check if you are buying any such items.(06-29-22)
INFLATION!….. It’s in our cards these days. We try to keep up on pricing - inventory for our services, our modifications but we might fall short on occasion so please be sure to confirm pricing with us when you order.
Power MOSFET replacement ……… is becoming a problematic issue with the announced “END OF LIFE” status for the Exicon metal can/TO-3 style devices. If you have a Hafler amp you might want a set for your amp if they are available. We will investigate the adoption of the TO-247 size ‘plastic’ devices like we use for our PA-8 mod for application in the DH-500/XL-600.(05-09-22)
Our mod workload……..dictates that we must shut down ‘custom’ work for now and perhaps permanently. Some exceptions may be made, for instance, a modified Musical Design product or custom work that Musical Concepts previously produced. If it isn’t on the website ‘menu’ it is not offered for now.
