I did in fact post a photo tutorial - #5683 - which should hopefully help you. You can either leave the base loose, or glue it back on - you'll need a thick glue, and be careful it doesn't run down into the pins. Either way, you will need to make ABSOLUTELY sure the 'church windows' match up to maintain proper pin placement...I found the base could almost fit convincingly onto the pins in any order!
Hope all goes well...it'll look SO much better, lol!
Any questions/problems just let us know...will be back on tomorrow...
Thank hypnos. Might attempt it sometime in the future. Seems like a fair bit of effort though I do like to see tube glow :) Why do the tubes have the casing in the first place? does it help to keep them cool? I was apprehensive of trying these c3g's due to the rave reviews and didn't want to be disappointed though I'm glad you and others recommended them. Along with the 6sn7's this amp is in another league now. Just got my sylvania 1952 'bad boys' 6sn7's to arrive and I think I'm set and wont be buying tubes (for the LD MKIII anyway) ever again unless another incredible tube like the c3g gets discovered.
