The reverb tank was mounted by two aluminum cross bars that connected to the top edges of the chassis, so that it hung down into the center part of the chassis. If you look at the top edge of the chassis you should find the 4 holes where the cross bars connect to it.
As for the noises, you're talking about a 40 year old amp. Modern transistors are much quieter now, so if you continue to replace the old ones, you can reduce the noise a bit more, but don't expect total silence from an older design.
As for a low-pass filter to remove the noise, it can be done, but it will alter the high frequency response of the amp's audio signal as well.

Many 45 year old SS amps like Sunn's used a high end and low end frequency limiting phase inverter transformer to drive the main output stage which Kustoms stopped using with the 1968 and up models.
Along with the new direct coupled amps came more hiss.
When all is well with these 68 and up Kustoms even with good as manufactured Transistors the noise floor should not be a issue unless your recording off of the RCA jack on the rear of the amp.
Fact is the more coupling caps you have in the signal chain, the more steps of phase change takes place and before you know it the nice natural tone of a guitar you may like is gone, or the amp is on the edge of oscillating and sounds Nasle as hell like the early Mesa amps!
Add more stuff / circuits to your amp if you like , but for me be it a SS or tube amp I will live with a less then great noise floor thank you!
