Wanted to bump this for any new comments. Anyone try the Telefunken 6922? I bought Amperex gold 6922's about 18 months ago and my initial reaction was they were slightly more bright than the stock ones but kept them in to let them burn in and never removed them. Just looking to try something different. Thanks. |
@scm I didn’t have that upgrade when I had my PH9.0X, but Dan offered that rectifier tube and circuit with a lot of his other units, a few of which I owned. A rectifier-based power supply will deliver additional harmonics and remove any edge you may be feeling/hearing in the unit. Consider it a form of additional power filtering that both improves current delivery in some areas and sags in others. The result is a more musical gelling and oftentimes more realism. Dan provides a sovtek because they are readily available, but if you swing for the upgrade be prepared to invest in a more premium and costly rectifier. My favorites in his power supplies have been the Philips 5R4GYS, which deliver unparalleled holography, harmonics and bloom. The EML 5U4G is also very good, perhaps more linear. I’ve tried at least a dozen other tubes, but I tend to go back to one of these. I no longer have any units with a tube rectified circuit, but I still hold on to these tubes in the case that one day I may have another. Hope this helps. |
blisshifi....Thank you very much for that information.I`m going to go ahead and have the upgrade done.I`ll let the stock tube get some time on it and then maybe shop for another tube once I`m familiar with the Sovtek sound.
Thanks again Steve |
