Tubgroover: I was told that most of the added weight was in fact a result of the feedback setting so perhaps you are correct concerning the tube. I did not do a comparison with low feedback and stock tubes vs the Telefunkens thus I can not speak to the actual sole contributions of the tube, though if I were a betting man I would say that added nothing but goodness to the sound :)
Indeed it is a flexible device and though I did not like what I heard ini stock form, I did hear potential :) I'm pretty good about yearling a product and even if it is not my cup of tea right away, I can sometimes hear it's potential to be much better. This is why the ZH 230 was invited back into my home :) it paid off!
Thanks for the info concerning the effects of the tubes...
