paulk Posted March 2, 2023 Posted March 2, 2023 Hi Steven valve, Thanks for the info. I'll definitely look into those. Unfortunately I'm not that knowledgeable about what particular valves are better. I'll check these variants for sure. Regards, Paul
paulk Posted March 2, 2023 Posted March 2, 2023 @xlr8orHi Kirk, Sorry, I should have been more specific in the gear Im using. At this stage I would like to only change the 12au7 valves in my PS Audio BHK preamp. I know these suit many variations of the 12au7 valve but was hoping you would be able to help get the most suitable valve available. It seems the consensus of opinion on the stock Psvane 12au7 in the BHK pre are a bit bright and edgy with most people tending to tube roll them. That's where I was hoping you may find something. As always any help mostly appreciated. Regards, Paul

I don't think an E80CC will fit into the PSA BHK Signature preamp as it's height is too tall. https://www.ebay.com.au/itm/385455547161 Edited March 3, 2023 by xlr8or 1
paulk Posted March 4, 2023 Posted March 4, 2023 (edited) @xlr8orHi Kirk, Thanks for the heads up on these. I have little experience when purchasing off ebay particularly when it's going to auction. I also sent you a pm. Thanks again. Paul Edited March 4, 2023 by paulk

If you're wanting Sylvania made 5751's, it's the triple mica black plate ones with standard pins you want. The Raytheon windmill getter (often labelled with red print) from the 1960's is the best sounding one of the lot. https://www.ebay.com.au/itm/385299826072 Edited March 4, 2023 by xlr8or 2

I got the gold pins but they are ordinary so I was wondering what the fuss was about. Yep, Raytheon windmill getter I got two or three pairs of those 1
Guest Posted March 9, 2023 Posted March 9, 2023 Just a note about being careful when tube rolling in the bhk. You would be best sticking to 12au7 and direct variations. And also 6922 and 7v tubes are fine as long as you adjust the voltage and current jumpers inside the unit. If in doubt have a look in the PS Audio forums as people have made lots of enquiries on there about suitable tubes. It's an expensive preamp and is be super cautious trying anything outside of the designated tube types.
