6k6 use in fender 63 reverb reissue
Can i use a 6k6 in place of the 6v6 in my fender 63 reverb reissue without any mods.If so what change in tone will it produce.I have a few nos 6k6's and i would like to try them, but i don't want to blow up the reverb unit.thanx in advance for any advice.

yes, should work. I have (in my reiss.) and nothing untoward happened. I guess maybe it sounded a bit less distorted (been awhile since I've used it).
Book Of The Day The Ultimate Tone, Volume III by Kevin O'Connor
Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn’t change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the “iconic” amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product. Eyelet-board and chassis-mounted tube socket construction is used throughout, for easy servicing and modding. TUT3 is very accessible even if you cannot fully read a schematic and is a "must have" if you are going to build an amp for your self.

I believe that's the orginal tube used in that unit (in 63) !

that's correct. 6K6 has lower power ratings etc than 6V6 but in this app it does not matter. As long as your B+ is within range and the idle current is cool you should be fine. It only dissipates 8.5W (vs 12 for 6V6GTA) I think the RI ships with 6V6 bc no one makes a 6K6 anymore, that's all.

I prefer the 6K6 in my reverb unit, an original 60's w/brown tolex. I have to wonder if there might be an easy way to detune the circuit so that a 6V6 would sound as good. Something I've been meaning to look into before Randal Smiff does it and patents it.
