Preamp help please!

I've had some very disappointing experiences with recently purchased Psvane WE101d, two failures, one after around 25 hours and other DOA. I no longer know of US or Canadian source for Psvane, both mine purchased from China, don't trust Chinese sources! Until Psvane has good source here I'm done. Perhaps Israel has source?

So, I've gone to Linlai Elite solid plate, this is very good tube, about on par overall to Psvane, Psvane a little lighter, airy in highs, Linlai more solid in middle. For a bit of time thought I liked Linlai mesh plate version, over time heard a bit of glare from mids. Should have listened to Israel on this, it was on Rachel's (Grant Fidelity) advice I purchased in first place. I have Shuguang standard, that tube not in same league as any of these, not ugly sound, just blah, lacking resolving, transparency.

The WE 101D tubes are an improvement but probably not what you are looking for. You can send it to me for a major upgrade and it will be a major upgrade. Tubes can change the flavor of the sound yes but for a bigger improvement, better capacitors and resistors will be more beneficial. My company builds 101D audio tube products as well as 6SN7 tube products so we are very familiar them. We can even improve your Supratec.

Happy Listening

btw, do you have a simple tube tester?

"you'll be happy for the rest of your life if you make an ugly tester your wife".

name that song!

"Get an Ugly Tester to Marry You."

ps I have 2 tube testers. For an old scope. I use solid state.

What gear did you use the Mk1 with before, and did you like it then?

Could it be a mismatch with the Pass?

If you don't like the sound I would just sell it and purchase a tube preamp with considerably more tube rolling options.

Being restricted to 101D's (or 6H30's for the matter) is not a good place to be in, IMO, as one of the great benefits of tube gear is tailoring the sound with different tubes.

Perhaps look into the extremely well reviewed $1300+ (depending on options) Linear Tube Audio MZ2 preamp/amp as you could sell the Mk1 and have enough leftover to cover the repairs on Supratek.

I use inexpensive Bottlehead kit gear with really good old production tubes and get really good sound.

Probably the only person who has run Visseaux (engraved base) 2A3's in a pair of Bottlehead Paramours.

Coach: I too have a Sit-3 and Cornwall IV’s. I am using a different preamp....I live in Maine (!) and if you’re close by, you’re welcome to come by and have a listen... Preamp is a Black Ice Fusion 360 which uses a 6SN7 tube.....
