    Tried the Knutsen-Amp at rehearsal with the blues band two days ago, through a Behringer 4x10 cab. Unlike my Valve Jr, this amp delivered just enough clean volume right before clipping the power tubes. Nice, compressed and slightly gritty sound with my P-bass. This band isn't very loud, though.

    I'll put in a good word for the CTM-30. I really need to take a picture of mine in its natural habitat (coffeehouse, wine bar, brew pub gig) so I can be officially a low-wattage tubester. Turned up to an appropriate volume for such venues, it's just pushing the edge of sweet tubey saturation.

    My two current low watters,
    Bogen not a bogen chb100. I got this one from craigslist free listings in a pretty rough state. Re-capped, re worked bias circuit with bias per tube, completely reworked preamp, new EH 7868 outputs, lots of gain and lots of fun.
    IMG_3709.JPG IMG_3720.JPG I need better pics of the cab but here's an old one from before I modded the head. It's an old Silvertone hifi woofer, re-baffled (fitted for a 4ohm 15) and foamed.
    IMG_2368.JPG And my latest low watt amp is a custom built 5f1 circuit with gain/volume and a 22k on the input rather than the 68k

    There's also this stupid thing, it's a Gregory Mk V. It is one of the widow maker amps from back in the day, ie no fuse or power trans = very unsafe.
    I looked around a little and there are ways to make this thing relatively safer but nothing I liked the look of more than just gutting it and starting over. I re-capped it and gave it a test and yeah sound very meh so as it sits it is gutted.
    I was thinking something more powerful and a bigger speaker but I'm not set on anything in particular yet.

    Nice amps. And a pretty bass, too.

  9. What is the maximum wattage to be in this club?

    Will take pictures later, but I have the following setup

    Demeter all tube preamp into a Peavey 50/50 power amp bridge mono 100watts
    THD Univalve with a single KT88, Class A pushing 18 watts (as measured with a scope )
    Frenzel tube "Tweed Deluxe" with 6SL7 preamp tube 25 watts into 2 5881 (smaller output transformer). To get bassier, I use an ART preamp plugged into the power amp in, which also doubles as fx send (not a typo -t has a gain knob which switches the function from FX send to power amp in)

    I still have my 1967 blackface Bassman amp. Its 50W of tube power played a lot of gigs back in the 70's, including the band for the Jr. Miss Pageant in a 700-seat auditorium.

    It won't see another gig, because I have a Fender Bassman 100 V3 that weighs less than this head by itself. But it's handy for practice because I can use the Bass input for my instrument and input a CD player into the "Normal" input. I have individual volume control over each.

  11. I have two, a 50 watt '67 silverface bassman with original large 212 cab and an Ampeg Bassamp 835 that puts out 35 watts with one 15", has an old Utah coaxial in it and sounds really good, the original Jensen is long gone, no pictures though they are quite far away right now, I should be back to the USA next month though.

  13. Sure I'll be back in about 3 weeks, I've had it for about ten years and just had it gone over by a good tech.

    Sounds like you qualify. Very arbitrary limit of 50 watts. Number for you?

    I have a Hughes & Kettner Bass Master (1x12AX7, 1xEL84, 5 lovely watts) that I use at home, running it through an old Italian 2x12 (Caldironi-Meazzi).

    Nice to see some new goodies here, I haven't checked in for awhile. I'm not sure if I put this pic up before or not. This is sweet sounding amp with bass or guitar.
    Here's a late 60s Guild Thunderbass about 50 watts.
  17. And yea, hey, @R&B I'll take a number, I'm pretty sure I've posted several amps here.
    My tube amps:
    Guild Thunderbass
    Sunn 200S
    Polaris, (DynaCo MkIII sunn clone)
    Stromberg Carlson Signet 22
    63' Fender brownface Pro
    53' Fender Tweed Deluxe 5B3
    2 60's Audio Guilds
    Gretsch Dual Twin Reverb
    And whatever I forgot. Lol

    Kirk Bryant those thunder bass amps look pretty rad, there was one on my local cl a couple weeks ago with the matching cab for $300:jawdrop: I had to let it go though as funds are tight atm.

    Part of the reason being as I committed to buying this,
    IMG_3810.JPG IMG_3808.JPG IMG_3812.JPG This was a friend's amp in for repair, said it was sounding awful. The right output label being burned is the first clue then on further inspection I found one half of the ot open. and with that news it was offered to me for sale. Plan now is to replace the ot, outputs, caps and do a general clean up of the messy wiring in this thing. Should be nice when I'm done with it and will make a good spare time project in the next month or so. :)
