    That is awesome, and isn't helping my DIY GAS for a project like this

    I'm particularly thinking about getting another Mesa Studio Preamp. It looks pretty simple on the inside, and might be a fun mod project.

    Studio pre is fairly simple to mod.

    You could even make it usuable as a multi channel preamp with a second vol

    Got the drill templates printed out last week, have this week off work so was going to get a start on drilling the chassis at least, and come to find out they're banged up all to fuck.

    Shipping box wasn't damaged so this left their warehouse in this shape, and both of the chassis' are dented in the same spot in the same manor, although the one pictured is the worst of the 2.

    So Next Gen music is shipping me 2 replacement chassis' and said I can keep the old ones for non critical projects, sell them or throw them out, it's up to me, so pretty happy about that.

    Not sure I'd use them for much given the spot welds in those corners are busted, do have a friend with a welder but he's a mechanic by trade, not a welder and I hear aluminum is a different beast to weld. I could straighten it out decently with my vise I think, and use a mallet to whack it back into shape, just not sure there's much else to do with it.

    It's alive! And so am I.

    It's cool, I dig it, but it's literally too fucking loud... I have an easier time dialing in low volume sounds with my 2/90/2 which is unexpected.

    It's 5-7 watts, not sure how to measure exactly. I have my trusty multimeter but no idea where to measure on the output transformer, imagine I'd have to measure resistance and current and calculate it with Ohm's law or something.

    What's all that empty front panel space for? Mod switches?

    Haha, nope, although maybe in the future. The drilling template is absolute shit for the Hi Octane. They expect you to drill a metric fuck ton of holes in the chassis so you can upgrade in the future and fuck around with it. Like the drill template had an extra tube socket hole that was a different size in case you mod it into an EL34 amp in the future, etc. If I had been thinking when I did this one, I would have shifted the pots over a couple inches to keep it away from the AC current on the switches/lamp to reduce noise, etc. Probably would have spaced things out a bit more as well.

    Oh well, it's my first build ever, and I have parts to build a second one. I think I'm going to put an extra 12AX7 in the next one. I put a cold clipper on the gain stage right before the cathode follower for the tone stack, and that didn't work, need to actually build the amp around that. I pulled that out and put it to it's original value. It has a bit of noise when turned up, but at bedroom levels (essentially .5 on the master volume) it's pretty hum free.

    It sounds good, but not great. Just happy that it works and I didn't electrocute myself I might look into seeing if I can use a lower power tube for the next one for the power tube, just so it's actually quiet.

    I never owned a low(er) power tube amp before, and honestly it makes me question by 50W and 100W heads kind of became the standard. I can't even turn this thing up to 1. The thing that saves me with the 2/90/2 is that I can dial back my preamp volume controls and have a usable range on the power amp volume knob.

    Back when my garage wasn't the only space for my guitars, amps, and my office, I could regularly run my 50/100W heads upwards of 3(!) through my favorite 4x12. Now, I live in the bullshit city with goddamned neighbors living two fucking ballhairs away
