What tubes for ST-70

Well guys my tube rolling is done for now. In the end i settled on a pair of RCA 7199's, a quad of winged "C"' el34's and a Mullard fat base gz34. While the 7199 and el34 tubes were an improvement over the tubes i had to start with, the gz34 brought the amp up to a new level.
I could not belive the improvement i heard after i installed this tube. The bass is much more full, the treble very smooth and the mids are to die for. I'm just glad my local dealer doesn't charge the crazy prices i see on the net for these tubes. But in truth if i spent $150 for this level of improvement i wouldn't be disapointed.

In this case- it's a pleasure to say, "I told you so!"(re: the Mullard in the power supply) If you're handy with a soldering iron, replace the Black Cat coupling caps with something newer(auriCap/Multicap/DynamiCap to list a few good, reasonably priced ones), and you'll find even more music hidden in your discs. Enjoy your tunes. =8^)

Well Rodman, you were right thanks for your advice. About the caps, this is not a stock st70. It has been rebuilt from the ground up. The only thing that is original on it is the transformers. From what i can see from the top there are solen caps in the 7199 board. I will have to open it up to see the rest of the components that are in there. But for now it sounds so good i don't want to waste any time on taking it apart. I'll just listen for a while. :)

If it's using the 7199: It's probably still the stock design board, and the signal path components are on top(no need to open it up). Solens are way better than the oldies too. Happy listening!
