"... Hi Mark, just wanted to thank you for ...  the RCA 5751. My God, what a tube! I've never used one before and the difference is just amazing. Makes my '66 Super Reverb just sing and brings out the clean tones beautifully while still attaining that nice breakup that Supers are known for. This tube with a Stratocaster is pure Heaven!I had a Mullard ECC83 in the V-1 spot. It is now owned by this 5751! I can see why Stevie Ray used this tube! Thanks once again for all your help and turning me on to yet another tone color through the use of incredibly fine tubes! You guys are the best and not just on the 'net. Jim ..."
