Nice but....
1 of 1 found this helpful This product seems to have a motor cogging issue. It took a firmware update to make it driveable but the issue remains just not as severe. I had to buy the programmer to update the motor controller.

Vintage Glass
Good vintage product, only one of six tubes exhibited some excessive noise characteristics but my application for these tubes has them on the front end of a sensitive solid state amplifier so this in not uncommon in my application. Great packing double boxed drop proof.
