If you love to rock out these things are nothing short of epic. Russian built, point to point wiring and phenomenally loud. I had trouble for years finding a 4x12 that could handle this beastie. Peavy 5150 quad works, a 4x12 Behringer 400W works well but I recently purchased the correct Sovtek 4X12 which is rated at a whopping 600W. It makes sense now that Marshall 1960A's are hopeless with this amp. If you can get one, buy it. These should be worth well over $2000 aud. Rare as hens teeth, single channel super amp
. Highly recommend.
