I knew for sure that with all you creative folk something like this was coming.
For the tube rollers out there, did you know you do not have to remove the back panel of the Monique Rack Mount to get access to the tubes through the top? Just remove the four black screws on the sides of the top, and the two silver-ish screws in the top. Then it slides out of the way easily.
If you experience any mid to high frequency noise with non-metallic based NOS tubes that you want to try, just get yourself metal tape to wrap that plastic/phenolic base. Trim it nicely with a sharp knife. Applies to any octal tube other than output tubes. Do not do it on output tubes. Best is tinned steel tape from an electronic equipment supply (expensive) but the heavy aluminum stuff for air conditioning ducts works too. Copper tape looks cool.
The "tube holder" clamps on Monique are less to hold the tube in place and primarily to make electrical contact between the chassis and that tube base.
The above is a very small detail that is unnecessary in most cases, but it can be significant with some tubes and gear. Nice thing for B-15s too. It is a trick from the audiophile world.
