    Sovtek EL84M

    Best surviving EL84 I have dealt with road-wise.

    NewSensor will match them in quads/pairs/etc.

    No way I'd buy one brand new. Too many being passed between hands at any given point. Ideally, I'd like one with some years on it, a recent service, and a clean face.

    Thanks

    Honestly, I don't have a rec. I've only looked at the options for bass amps that I've owned.

    The newer ones (post mid/late 90's) have a white lettering, the older a creamish looking color that looks smoke-stained. Those are the bad motherfuckers there... when boogie cared. Make Sure the EQ faders are not seized, if they are HARD that's fine, not seized, re-lubricate with an electronics safe Teflon lubricant... Good to go. Use that stuff in old moogs, works great.

    Finally finished! One of my father's day gifts was some free time in the garage this weekend. This is the first time I've been able to work on an audio project this year (been a crazy busy 6 months).

    It's a slanted 4x12 using Marshall 1960a dimensions, but with Tolex and grill cloth for a fender twin reverb. Speakers are from WGS (vintage 30, et65, reaper, reaper 55hz). I've got them on switches so I can run all 4 or any combo or single. I integrated the switches into one of the handles to keep them protected and visually unobtrusive. Input jacks are neutrik TRS and speakon in parallel. Still waiting on some nickel corners to help cover my seams where I had to trim tolex.

    Excuse the dust and clutter in the pics (a lightly textured finish on that maelstrom box was a bad idea). I've just started getting the den set up as a man cave.

    Congrats on the finished project. Looks great with the lunchbox sitting on top. If that grillcloth has some wrinkling, a hairdryer should smooth it right out - worked perfectly on a bass cab that had a 'dent' in it for me.

    Interesting, the use of four different drivers.

    Is it open or closed back (I gather the Speakon jackplate is on the back, but not sure if it's a partial back)? And if closed, how do you feel about the varying enclosure alignment when you use fewer than 4 drivers?

    Happy Father's Day, btw.

    Thanks for the hairdryer tip, it is a little wrinkled in the photos (didn't even notice in person until I saw the photos).

    It is closed back and I've worried about the varying alignment. With all drivers on it is about 1x Vas, obviously that factor changes with fewer drivers on. I'm thinking the very low power level being applied may moderate any impacts, especially since this will not be playing particularly low.

    The reapers will likely always be on. The et65 and veteran 30 are the ones that will switch on and off. The et65 in particular is a little bright at times. Thinking I might try a paneled back at some point so I can vary between closed and open. I've given thought to isolated chambers, but to be honest, I just wanted to get it done and start playing.

    The little head is a Blackstar HT1-RH and it is awesome. 1 watt so it breaks up nicely at moderate volumes (amazing how loud a 4x12 with 1 watt can be).

    So far I love this combo. Even my wife complimented the sound versus both my little 15 watt Marshall and my prior Fender Hot Rod Deville.
