SDS board is a pretty good idea. Might want to get board and order components from mouser. +1 on McShane. Love the PIO russian caps in my Fisher. John

When you say the tubes are running "brighter," do you mean the orange of the filaments or are there other parts of the tube that are beginning to...

Yep, Jim will help you with individual parts. I think he'll put a kit together too, if you wanted to go that way. Triode Electronics also has a handy circuit board called the SDS board that will replace the can caps and the bias caps, if you want to look into that. Lots of info on it here in the tube forum. Just use the "Search this Forum" tab at the main page of the tube forum to find loads of Fisher threads.

Great! So the diodes are good but it wouldn't hurt to replace them. To start off with, just do a good cleaning of the switches and tube sockets and then eventually you will want to do a total recap job on that puppy and maybe get the tubes tested. Out of all the tube and solid state junk that I own, I have yet to acquire a Harmon/Kardon tube amp. They are known to be very good and some day I hope to acquire one of them! I'm still...

im with jaymana on this one. i use plastic storage bins. i dig when i need stuff and its like christmas everytime. the prized finds go into smaller bins for easier retrieval. i dont toss any good tubes. tv tubes may be plentiful know but that wont always be the case. unlike many other electronic parts, tubes are very sturdy and can be stored in hot or cold climates without much worry. my stash is about 8k.

For the 6AQ8, check your chart for 6DT8. That's a direct sub for the AQ8. And @ 1/3 the price too. I had to figure out the specs for a 76 tube the other day on my EICO 625 tester. There should be, in the instruction manual, a procedure for a tech to spec out a new tube before the new sheets had come out. If there is, take one of the tubes you know is weak and use that to get the basics down. Then tweak the shunt spec with 4 or 5 good...
