    6f5p's?

    10 watts of real rms power is plenty if you have efficient speakers. [which I don't]

    Copper plate GM70, Russian 845 equivelent. They are run pretty conservatively single ended, and can put out double that if I I run them off the 16 ohm tap. I have some 99db GPA (Altec) 604-8H-III in ~300 liter mass loaded transmission line boxes I built.

    Also have a 2A3 amp i love the sound of, a pair of 45 monos, and dirty little EL84.

    Nice, I bet it sounds sweet.

    Someday I may have to put a SE amp together for the house.
    It pretty much takes PP to drown out the machinery in the shop sometimes....especially powering 48 inch BG ribbons.
    Can you use FLAC files?

    I bet. You should look into some Altec A7 speakers. Very efficient, great sound though not as extended top and bottom as they are essentially old theater PA system. But, sweet midrange. I have seen some shop setups where they are very effective!

    Yes, I use FLAC. I have been meaning to buy a better DAC than I have, but recently the audio time hasn't been as much as a couple years ago and I tend to listen to vinyl. I built my TT as well - and old Garrard 401 (no Norton parts) and a handmade arm a friend here in NZ made. Sounds awesome.

    I will start sending you some dropbox links.
    I just picked up around 900 mint LP's over the weekend and will be slowly digitizing them.

    Sweet. What do you use as an ADC? I have a Hagerman Ripper that I have done some digitizing with, mostly as a good way to A-B changes in cartridges, SUTs, tone arms, footers, etc.

    I have an ADC GT40 for A to D which I like and several D to A's, none of which I am real happy with.

    Right now I am using a modified Azus Essence PCI card which sounds pretty good when the software is cooperating.

    Yeah, I have been looking at some Schiit dacs. I bid on one on e-bay but lost it a couple weeks ago.

    Send me an e-mail when your done with the dropbox so I can empty and reload it. Between my brother and I the dropbox is usually at it's limit...

    That would be a non-gimbaled unipivot gerbinator defangulator.

    Those Altec's look kinda like a pair a guy sold me in the early 80's, Not in big boxes like yours though. They came out of the Long Beach municipal auditorium when they were tearing it down, The date on the inside of the box says 1955. They also have some sort of metal box inside them with a bunch of wires coming out of it lol. We tried to blow them out years ago but no luck, still sitting in the garage. You guys make me fell like digging them out and putting the stereo back together. :shock:

    No doubt about that -but with the CNC machine and a hot tub running anyway, the amp was barely noticed.

    Looks very impressive. What tubes are you using?

    I am using 6021's for preamp and inverter, 6bg6's for drivers with fet followers, and Amprex 4-250's for power in the video.

    I have moved to Penta Labs 4-400's after the video was done which has increased the power to around 1kw. Jim

    I used some Penta KT88s in a set of big parallel push pull monobloc amps I had. Penta relabel some great tubes.

    The Penta 4-400s I am using are NOS from the 60's. They are made in the USA but I'm not sure who made them. I know they are the same as the RCA tube from the same time.
    They sure are pretty though.
