This appear to be identical to those found on a Twin Reverb reissue, but if you can compare the measurements provided above to verify if there are any differences.

The mounting holes for these are oval to accommodate different center to center screw distances, so they are compatible with a number of tube sockets and types. We do not have sizing information on your specific amp however, so you will need to refer to the tech drawing above to confirm a proper fit for your amp.

This is a solid octal-base tube clamp with a firm-enough spring tension to secure my upside down hanging 5U4GB rectifier. Recommended.

This clip does the job. Exact replacement for many amps. They are tight, and really don't like to let go of the tube, you need to use two fingers to push quite hard while using the other hand to remove the tube.

These worked out great, easy to install. Great for Amps with inverted tubes.

I was a little put off a bit the price of these until I received them. It seems Belton has spent considerable effort on upgrading sockets for, and the retention of, inverted tubes.

These fit great and hold my 6V6s tight in my Princeton Reverb.

Very Strong grip on the tube, almost makes changing a tube a two man job! Great for rectifier tubes and power tubes
