RE: My experiences with new M-60 Mk.3.3s, good and not-so-good

I won't comment on the parts swapping. But it seems to me that I see threaded recesses in the bottom of your chassis which might accommodate the threaded male ends of audiophile "footers", if you are of a mind to do that. I wonder why feet of some sort were not included in your shipment.
I am sure you realize this, but go easy on the dampening materials lest you impede the cooling of the amplifier via heat transfer direct to the metal chassis. The cooling is not entirely dependent upon the slotted air vents.
I will send out your 6SN7 this week. Thanks.
