I assume you can't use 4-volt rectifiers? If so, there are some nice European AZ4 and AZ12 rectifiers that can provide 200 mA.

Not sure. Maybe with an adapter Tomas?

My rectifier socket has 5 pins.

That adapter would need to have a resistor inside it to drop the voltage down to 4V. Would work but could get very hot inside the adapter. Not recommended.

So no one has an opinion on these crystal white Ascension speakers that are specially made for tube amps? 95dB is very efficient in my book. 10" woofers !

My Tektons have 10" woofers and are 98dB. My dogs woof louder than what you're looking at.

Also a good one on the VPI forum:

Must be as many ways to clean a record as there are tube rolling combos in all of UT's amps Personally, I clean the record in a DIY ultrasonic machine and then rinse/vacuum/dry on a VPI HW-17. The above thread has made me consider also doing a pre-clean on the HW-17. I have about 30 new records that I'm waiting for a rainy day here to clean.

Just reading the first post, $143 for a 2 micron filter? Holy cow. I paid $11 for two 1 micron filters. Guess I'm doing it wrong.

Oh yes tube phono is the way!


It sounds great, but @leftside recently had an LCR phono custom-made, this is a more esoteric type of tube phono, the bee's knees, tricky to design, requires specific tubes and custom chokes. I collected some E55L tubes, maybe seven or eight pairs, great for the LCR phono, it's on "the list" of things to do, but first tube DAC.

Couldn't agree more, except to nitpick and say it's the only way.

Mine has the mahogany colour and is two pieces. The separate power section takes 2 EL34/KT66 and a GZ34 rectifier.

The only picture I have of mine is at night.

I've never heard a Supratek, only heard of them. Considered end game by many.

There is no such thing as end game until all audiophools are dead and gone!

There will be no end game when until then and endless are still around.

I guess we'll just have to be endlessly patient until then.

Mick from Supratek is also a great guy to deal with - as with the custom amp builders on here. We've become friends as he is also a downhill mountain biker.

Not forgetting he's an Aussie.

Anyone have experience how Citadel or Oblivion is comparing to GSX mk2 ? I have GSX, just looking something new and different. Thanks

@joseph69 has both at one time. https://www.head-fi.org/threads/oblivion-ultrasonic-studios.902926/post-15880832

Here are 4 links regarding their differences based on listening to the Utopia.
