What are the units sitting on? A spongy footer might do it??
The Tele is a little lean for my tastes.You might look at the Mullard 4004/M8137.These have the body/warmth with a little more "sparkle" to the top-end (as compared to the standard "ax").
If you can source a pair of the Shuguang G8/G9 triple mica 12 ax 7s,you would probably be happy and at a much lower cost.These are a little hard to find,as they have ceased production.What they produce now,I can't comment on (not heard).
