Is there such a thing as a stand alone 300 watt tube power amp ?

    Trust me when I say that the Demeter vthf300m will make your zephyr sound like the voice of god. It is the most stunning power amp I’ve ever heard for bass. I have some Arkham stuff, can’t imagine how good they would sound into the Demeter tube amp.

    Yes. Yes there is.

    The Peavey 120/120 is a beast as well.

  3. You don’t need 300 watts tube power unless you wanna be deaf. Here some other options

    Mesa Carvin peavey all made rackmpunt tube power amps from 100 watts up bridged. Mesa and peavey I believe go to 250 or more. Peavey are cheap and still solid. Mesa are decent but will have the standard Mesa small iron transformers. Carvin I’ve heard are decent but out of business.

    McIntosh if you wanna sell your car to get an amp.

    Another vote for keeping your eyes peeled for the Peavey Classic 120/120. There was a Classic 120 also (single channel). They used 6L6 tubes.

    Rivera made a TBR5 which was stereo at 160W per side.

    You could probably commission at 300W build from Verellen Verellen Amplifiers - Amplifiers , Siegmund http://siegmundguitars.com/bigboy.html ,...or any number of other amp builders.

    A custom tube amp is going to be heavy and expensive though.

    IMHO best bet would probably be to track down an old Ampeg or Mesa.

    The Zepher is a hybrid, It uses Mosfets for output. I would expect they design all the tone in the preamp before it hits a power amp. It should work great with any power amp.

    In audio tests Louder always sounds better. So maybe it's that the Fender was louder when you tried it.

    Between power amps like a Tube McIntosh or one of their solid state models - there is not sonic difference that humans can detect if the test is set up fairly to account for gain matching, ...

    Sometimes power amps cost as much as the actual head. You can run through the FX Return of a Mesa 400/400+.

    For a moment when I was trying a pedal preamp rig I owned a Mesa Coliseum 300. It was more like dual 180w channels but loved the look of it. Pedal rig wasnt my thing, went back to my typical Mesa 400/Sansamp in FX loop setup which is still my all time favorite for what I do.

    I always thought the Strategy 500 looked fun.

    FYI, per the schematic, the effects return on the Bass 400 is after the tone stack, but before the graphic and master volume.

    Yup, Mesa Boogie made several Power amps back in the 80's and 90's. look hard enough and you can find them: M180, M190, Strategy 400, Strategy 500, Coliseum 300.

    One more thing to add...

    The Peavey 120/120 is the more neutral sounding. The Ampeg SVT definitely has it's own flavor and it's even more pronounced when overdriven.

    Do keep in mind to read the instructions before operating the Peavey. It's a true dual power amp with dual xlr out and preamp inputs. Make sure to review before you bridge the amp!

    You are absolutely right, ensuring that levels are identical is what I did when I was running frequency response
    sweeps of both & laid one trace on top of the other. I have been conducting audio comparison tests for close to
    50 years now, & know exactly what you mean.
    Currently the Zephyr is used with a Lab Gruppen FP3400 & is stunning. But when hooked up to the
    Bassman 300 Pro thru' the FX return, the Master volume is not functional, so I had to max out the Pre Out &
    Gain control on the Zephyr,to get sufficient volume, which would not be enough for louder gig levels, so the Fender was definitely not louder.
    The tube power amp definitely has character & a sound quality that is difficult to describe, but those who can hear the not so subtle differences know what I'm talking about. Don't get me wrong, I love Class D power amps.
    Because it sounded so good, that is why I want to obtain a separate tube power amp with a Master volume control to hopefully maximize the glorious sonic qualities of the Zephyr.

    Great note, I think it is a lesser known feature and it is something I enjoy about it. If you are running a preamp into the FX Return it offers an extra stage of shaping (good for compensating for room or cab voicing). I use a footswitch to control mine (note: only a no-light basic switch will work).

    For new:
    The only one I know that makes a 300watt tube power amp is Demeter. VTHF-300M Tube Power Amplifier

    Otherwise, get an Ampeg SVT or Ashdown CTM-300

    Not current production:

    Still not many choices for just a 300 watt tube mono power amp.

    I would probably recommend against the CTM300 in this instance. It's a great amp, but the effects loop is before the tone stack and the amp has a very strong baked in sound. With an SVT you can plug straight into the power amp and bypass the preamp.

    I have never heard of a FX loop before the tone stack. Did not know that CTM-300 is like that
