The BH-220 specs include a 240- watt output at 4 Ω (150 watts at 8 Ω), solid-state preamp and power sections, a Volume control, a Tonal Balance control, an Enhance switch, two inputs, a power-amp input jack, two speaker outputs, a headphone jack, an effects loop, a 5-band EQ section, a balanced direct pre-EQ XLR jack, and a post-EQ line out.

The XB-15 has a unique design that features a speaker cabinet and protective carrying case. While the speaker cabinet sits inside the case for travel, the cab rests on top of the case when in use—and the case actually becomes part of the speaker cabinet. This allows for “clean open E 40 Hz fundamental notes unmasked by overtones.” Specifications include a 250-watt power rating and an AMP 15B-8 15" speaker with a 5 pound, 5 ounce magnet.
EXCELLENT CONDITION !

In the early 70's the Aussie's used Fender, underpowered, Marshall , adequate but stretching to keep up with Marshall guitar amps and the later choice was WASP.

I believe they originaled or were also made in NZ but the small print said Holden-Wasp and the grill badge simply said WASP.
Mine was a 200 W with double stack (8x12"), They were all tube or valve as we call them. Loud and farty but cut through the mix well. There was also a 100W version but you never saw a bass player use one. Gibson EB3 was the bass of choice. There were a lot of them in Sydney at the time.
 
'71 Univox UX1501. USA made (for two years), 140 watts, hand wired, four 6550 (GE), loud, thick, glassy, great for bass or guitar, used by Jimmy Page and JPJ a few times. It's been great since I picked it up. Running it through an Acoustic 408.

Whoa!!! I had this same Univox head and the matching cabinet back (w/6 12" spkrs) in 1973. I purchased them brand new and after hauling them around for a couple of years, my back has never been the same! That head and the cabinet are HEAVY!!! And the sound of them was phenomenal! It's great to see someone still using that stuff!

I believe they called that amp Fat Albert... I wouldn't mind owning one. I had a 1011 that sounded pretty awesome. I wish I didn't sell it.

670 plate volts, 4 KT88, 3 12AX7A (I have a GE 5751 in the Brilliant channel, Philips JAN 12AX7A in the other two). The Partridge transformers in this are huge, larger than in a HiWatt 200, and the output is wired ultra-linear. Really clean tone compared to an Orange or SVT, but still unmistakable tube roundness and compression when cranked up. Accepts pedals in front of it beautifully.

Mine's still trucking-although has blown up a couple times

Had to replace the back board after an accidnet

Tech beefed it up to 230 watts.Has to inputs so it can allow for a wet and dry signal,which is great for fuzz.
 
My 1973 Peavey F800-B

A true solid state titan from a bygone era.

260 watts at 4 ohms, 410 watts at 2 ohms.

Those numbers are @ 1 % THD. Not bad at all for it's day. :bassist:

In it's original configuration, driving dual 18" Vega loaded folded horn cabs:

The late Leon Wilkeson of Lynyrd Skynyrd can be seen with a couple of them stacked on top of a mass of Peavey cabs on just about any live performance in the '70s.

More recently Jesse Keeler of Death From Above 1979 got part of his unique sound by cranking the built in distortion on his F800B (and running a clean signal through a separate Acoustic rig).

I had one of these too got it at a pawn shop with a homemade 2x15 cab. It was eventually eaten by a basement studio somewhere beneath Cleveland.

Really want one of these so bad. Has the OT been rewound in this?
