The 807 is one of my favorite tubes in my Firebottle. I have some 5933 tubes but have not gotten around to trying them. I should compare them. Might be a while before I do though.

It's easier to simply search this thread and peruse the posts. :thumbsup:

Noobie question re: LP-2030 preamp: I received the pre last week while in the middle of a move. Just now getting around to setting it up - now the noob question - there are 4 pairs of RCA jacks on the back. Dennis's info sheet only says "Pair of output jacks closest to the AC power cord". I take that to mean the output jacks are the pair closest to the AC power cord. The front selector switch says AUX - Mute - AUX - I take that to mean there are two selectable AUX inputs with a Mute setting in the Center position. That leaves 1 pair of RCA jacks un-accounted for. Here is my guess:
There are two pair of output jack (possibly for feeding a sub) and the two furthest from the AC power cord are AUX1 and AUX2 inputs.
Looking for some clarification or confirmation before I fire it up for the first time.

You are correct in your guessing. R&L x2 inputs. R&L x2 outputs in locations you describe.

Thanks @bearcity for the confirmation

It's much more difficult to have a conversation about a topic if it is buried in a monster thread. Forums work best when topics are grouped.

Mine arrived yesterday and it is :thumbsup: Paired with my Inspire 45/2A3 the combo is amazing. :music:

My Inspire KT88 SET is loaned out right now, so I'm running the LP-2030 in front of an Alan Eaton 45 SET. I've run the Sylvy 01As, RCA Radiotron UX201As, Cunningham CX301As (All 3 pairs supplied with the amp). I am currently running a pair of Cunningham CX371As. To my aging ears, all are excellent. My preference if I were to rank them would be 301s, 201s which are very close then the 371s. This is just an outstanding preamp/linestage and looking forward to hearing it with the Inspire KT88 SET when it comes back.

Don't forget it will work just fine with 12A/112A toobs as well....

Also consider the 5932, which is a ruggedized 6L6 like the 5933 is to the 807, but without the plate cap. It can be rolled right in to most of Dennis' 6L6 compatible amps. Dennis and I experimented with them a few years back, but haven't revisited them since.
