    Can someone reccomend me a smaller tube rackmountable power amp to go with my Mesa 400+? I am going to use this to power a Bergantino 210 with my 400+ powering my Bergie 610. Must be racmountable, and I prefer a mono block but would consider a stereo amp as well. I am most likely going to look used, so feel free to put in discontinued models as well. I would also need at least 100 watts, or something close to that. Also, what would be a good way to set this up? I was thinking of maybe taking the DI, but I think that I want to biamp and would also like to leave the DI open for the occasional PA. So, I think maybe a crossover going in after the FX loop with the lower freqs going back into the 400+ and the higher freqs (maybe at about 2000 hz? Reccomend a freq if you can) going into the extra power amp.

    The Carvin TS100 is bridgeable for 100 watts @ 8 ohms. Can use 6L6s or EL34s.

    mesa boogie and VHT make a whole line of guitar oriented all tube power amps. they're usually stereo, but should be around 100 watts or so.

    Anyone know if any Mesas are mono? I would like to use Mesa simply for sticking to a uniform sound.

    There was a Mesa M-180 (mono all-tube power amp, 180 W, 6*6L6GC) on eBay recently, but it was unfortunately snagged by yours truly. :bag:

    How many rack spaces does one of those take up?

    About hooking it all up: I'd send a full-range signal to the crossover from the effects send of the Bass 400+ and then plug the highpass-filtered output into the M-180 (or whatever power amp you'll end up with) and the lowpass-filtered output back into the effects return of the Bass 400+. I'd set the crossover frequency a lot lower (~500 Hz), but I think you'll find the optimal frequency empirically.
     
  11. I had a Silvertone 1464 class 60 watt guitar head that was great for bass.
    They made bass amps, you can find them on Ebay all the time from $100 to $400. Look at harmony central for reviews of all the different models that were made. Sears sold them in there cataloges in the 60s, but they were built by Harmony and work pretty well.

    Congrats! Those are great amps, used to have one before I picked up a Bass 400+, and loved the sound I got with the M-180 + a Kern pre.

    Ooooh! I'd be kinda scared to power a Berg 210 with a 100 watt tube amp. The Berg really wants alot more power than that, and I'm afraid when the amp clips, you'll need a pair of speakers.The NV cabs are sealed, and they love the lower powered amps(if you like it a little dirty). Also, Berg's horns are pretty revealing, and I don't think you'll like the sound of the amp clipping. I would at least turn the tweet off so you don't blow that up too. I use my NV610 with a Musicman HD-150, and it's wonderful.
    I'd recommend a call to Berg and get his opinion, but I think you'll find that he agrees.

    Thing is, I'm only powering the upper freqs with the 100 watt tube power amp, so I would hopefully expect a bit more headroom due to that. Also, if I am correct, the M-180 has half as many tubes as my 400+, which would mean more like 150 watts. I am really not planning to run this amp to clipping. I just want some extra highs live and a good practice cab. That said, maybe I should give Mr. Bergantino a call. By the way, this is the older 210 cab, which he recently replaced with his current one.

    Well, if you're going to use a crossover and only run highs, you might be O.K.. I'd just really pay attention to the clipping issue.
    Give Jim a call this week and see what his opinion is. I'd hate to see you blow up a driver.

    P.S. The D-180 does have half the tubes(6), but I've found them to be very underpowered in most situations. I've owned 3 over the years! I keep buying them cause they sound good, and keep selling them cause they're not "enough". The 400+ is a BEAST though!

    Do you think that the 180 would be enough to power just the highs though? Or should I really be looking for something with more juice? I'm going to give Jim a call later this week probabally.
     
  17. Just out of interest, 2x10 with 100 watt tube head = bad, yet 6x10 with 300 watt tube head = good?

    each speaker in the 2x10 will recieve the same amount of power at each speaker in the 6x10 surely?

    Bit more actually, as the power amp is about 150 watts. However, they are very different cabs. The 210 is ported and has a tweet, whereas the 610 is sealed and has no tweet. However, I think think (and hope) that the 210 would work well with the power amp.

    While the HT 210 does like lots of clean power I was suprised to find that I love the sound of it paired with my 100 w Ampeg V-4B. It is quite loud too. I havent run the amp into hard clip though. I have run the amp into hard clip with my HT 115 and the speaker was fine. It jumped around quite a bit but I wasnt afraid it was going to rip. Sounded good but definitely better with the tweet turned all the way down.
     
  20. Ah right, i spose they will be different speakers, but i thought speakers in ported cabs could usually get louder than thier sealed cab counterparts with the same wattage?

    I dont think you'll have to worry much about it, should be a belter :)
