The RA was clearly faulty. No mains filter should consume 2A!

Yep, must have been very faulty, although I dont see how it could consume 500 watts/ 2 amps, maybe the customers electrician measured incorrectly.
If you think how much heat that would produce

My valve amp only consumes just over 300 W

Anyway, regardless of that, the important thing is that the RA block sounded pish, and that Mark's block grossly outperformed it, solving a big problem for Theo - which wasn't surprising!

Just found this - yes, it was my block, and yes, the Mark Grant, once installed, is clearly better. There are 2 less fuses and one less plug in the way (the block is now hardwired to one of the dedicated radial circuit sockets), so there was obviously a lowering of impedance, but there is no doubt that the system was not performing as well as it could with the previous block. I've had the MG in place now for over 4 months, and I have no wish to touch anything else in the system: it absolutely meets all MY criteria.
