I understand PS Audio’s tube selection is limited to new tubes. I, however, just purchased three different sets of quads: (1) Siemens ECC88 (6DJ8); (2) Amperex 6922 (Holland) and (3) Amperex ECC88 Bugle Boys with the Halo Getter. Does anyone have experience with these tubes? How long do you have…

Their website lacks clarity in some respects, that’s for sure. I can only tell you I’ve read quite a few posts where folks have been happy with their purchases and they’ve been in business a long time. Any of the tubes I have looked at generally state if they’re new production, NOS, etc. somewhere i…

The Amprex 6922 tubes I’ve been using in the BHK 250 needed to be replaced and I haven’t been able to find the tubes I wanted to replace them with so threw in a pair of Gold Lions I had lying around. The GL’s in combination with the Apos 12AU7s in the BHK pre I installed awhile back sound amazing,…

I recently ‘upgraded’ to this combo of tubes too. I agree these sound amazing! With tubes, one never knows when it’s time to exchange them, but once they’re overdue and you do, you know!

I am curious whether your opinion of these tubes has changed? I might try them because they are comparatively less expensive, and due to your suggestion.

I confirm my opinion. I kept the same tubes. They correspond to my taste: clarity and flesh. Be carefull to use 1974 or 1975 tubes. Other more recent tubes do not have the same flavour

Hi everyone. Do you get the same impression as I do. I feel that PSA is heading away from tube gear. BHK 250 sold out, now 300. Tube preamp replaced with solid state. I got the M1200 over the M700 because of the tubes. Love my BHK 300’s as well. Will upgrade to the 600’s if they are fading away next…

For sure. Bascom was a big believer in Tubes and Paul let him have his line. I think the PGM line is Pauls new flagship and its going to be Solid State. The 600’s are the only ones left in production. Nothing announced yet for those.

Brian is correct. I don’t know how many of you remember the story of how Bascom and Arnie swayed me into including tubes in the (then) new BHK line. Short version is we had a shootout: my best efforts at a preamp vs. Bascom’s. The winner take all and set the direction of the company’s products for …

Paul does this mean Darren has also designed the PMG amplifiers? Will the stereo amp be first? Do you have any ETA ?

It does mean that. The new amps he has created are extraordinary—a whole new experience and one that’s got me scratching my head over how it could have been this different. My reference is the BHK600s, which I love, but this new design is a league above in ways I am still sussing out. Darren and I w…
