FS: Audion Sterling Plus SET amplifier

[Smegger68]

Decided to move this on as it's been sat in my spare room doing nowt for too long.

Mk1 Audion Sterling Plus with the nice chrome case. This one has been breathed upon by Anthony Mathews of tube Distinctions, who tweaked everything and threw a bevy of new parts at it about 5 years ago. I used it for 2 years before changing to my current setup, and it's been languishing ever since.

The picture is of the unit, but it has a different valve complement now. Power valves are Tung Sol KT-120s. i checked with Audion before purchasing them and they confirmed that the unit is suitable for powering the heaters correctly. Certainly I had no issues with them. Input valves are a NOS Brimar 6922 and a NOS Amperex Bugle Boy 5687. I can swap out the KT120s for either HotRox KT90s or Svetlana Winged C 6550s if you prefer, and I have a lot of different input valves if you fancy something different.

I'm looking for around £600 delivered in the UK :)

nice.. what output watts does it boast? might help sale18 Watts with KT88s or KT90s. About 15 with 6550s and with KT120s you might get a couple of watts more than the standard 18, but the best feature of those is that they are running well within their power envelope and thus will have a nice long life [emoji846]

Are you sure this is SET and not SEP? Pretty sure for 18w the valves would need to be strapped for pentode.

It uses the pentode in ultralinear mode. It's semantics really.

It’s a lot of amp for the money. Good luck with the sale.

For sure. Lovely amp.

Doesn't pentode vs triode change the sound as well as the power? I'm not sure many SET fans would agree it's just semantic.

Whatever. I'm just selling an amp here :)

[chris@panteg]

Interested, is it a power amp or does it have some line inputs?

It's essentially a single input power amp, but it does have a volume control and a gain stage so you can just use it as a single input integrated if you like. I used it for quite a while with one of those 4 way rotary phono selectors like this :)

Actually reason why I brought it up is that I'm quite a fan of Single Ended Pentode. My favourite Unison Research amp is the Preludio which is also a KT88-family single ended design. I bet this sounds super.

A good price for a very nice amp, I've owned a few Audion amps over the years, all of them excellent.

I bet this sounds super.The reason I've kept it this long is because it sounds great and I'm fairly loathe to sell it to be honest. But over 3 years of inactivity is too much [emoji53]

That's true. It might sound wonderful, but it's not a SET.

Thanks guys. Tom is the lucky new owner, hopefully he'll write up his findings when he's received it and had a chance to have a listen :)
