This is a 1973 Sunn 190B amp with the matching 215S speaker cabinet. I’d conservatively rate the condition at 8 out of 10. The amp is completely original with the exception of a replacement AC plug. The tubes all appear to be original: a pair of Tungsol 6550’s, a Mullard 6AN8 and an Amperex 12ZX7A. The point-to-point wiring is on terminal strips with neatly bundled wiring harnesses and high-end components for near military spec build quality. There is a bit of corrosion on some of the exterior metal parts and the chassis (I’ve cleaned up most of this) and a silver insert is missing from one of the knobs.
The speaker cabinet is all original, including both matching Sunn 15” Bass Transducers, handles, corners, feet and castors. Two handle caps are missing from the speaker cabinet. The Tolex and grille cloth on both amp and speaker cabinet are in excellent condition.
The 190B is essentially a re-badged version of the venerable 200S. The significant improvements include higher voltage input capacitors and diode rectification that help yield a tighter bottom end. This amp sounds just the way it should, with a round, organic sound that Sunn is famous for.
$750 cash, no trades. Email me for pix.
I'm located 1 hour north of Seattle. I can ship, but it will easily run about $150 or more.
Thanks!
