Post Subject: "Filter" vs. RC?Posted by Paul S on: 6/22/2010

Skushino, I'm afraid I posted that last when I was distracted. I admit I did not think twice about the MKP. I've only seen that style in fairly small values. What is the MKP's value, and why do you think it's "the" coupler, while the 'Cubes are else? What do you think the 'Cubes filter? I think I mentioned before that I could not read the traces when I opened the amps. I pegged the 935 for the output RC mostly because of its value and physical location, and I pegged the 950 for the RC bypass cap for the same reasons. Mightn't there be several couplers in a 3-stage amp? I hope one day to get a bright, skinny light between those boards, to try to backlight the traces, so I can read them without taking the boards apart.

FWIW, IMO, people should not play with their gear unless they have their own "good" reasons for doing so. I do have good reasons to swap the tube sockets; but - once again - I am simply curious about the caps.

Romy, the fact is, I have seen better parts but never have I seen better workmanship, so that is hardly a "bogus statement". And if you read the post again, perhaps you will notice that I was not - for once - posting just to bitch about the sockets, but I am primarily responding to Skushino to mention that to date I have merely cleaned the corroded sockets and then nursed them along with di-electric grease. You might remember for sure, but when I read your own post on the subject of lousy sockets, I thought I might know who the friend was (J?), and I wondered if perhaps my amps were once stored under conditons very similar to the friend's corroded amps. I don't think non-operation is always such a big plus for electronics unless they are stored appropriately. I have found old, stored gear with the tube pins pretty much fused to the sockets by corrosion, along with ruined wipers, etc. Careful regular use and maintenance seems to "preserve" the gear about as well as anything. As for the sockets, I'm basically over it, and I am "dealing" with it, but they are average to begin with, at best, and that's that.

Best regards,
Paul S
