The sound of these B15 combos is on just about every Motown and Soul record recorded during the 60s and 70s and have continued to be the choice of MANY artists across all genres to this day. I own quite a few of them currently and can't get enough. I gig with them all regularly. These blue checkered models are some of the most sought after B15 variations due to their visual association with classic players such as James Jamerson. This is a 65 according to the serial number. Likely a late 65 judging by the single baffle. It is working perfectly and was recently serviced. All the electrolytic filter capacitors have been replaced with original values to ensure its best performance but most of the passive electronic components are all original. All have been checked for drift and replaced if necessary. The power transformer was replaced a couple of years back. A new Heyborer properly spec'd transformer was sourced and repotted into the original can. That way it doesn't look goofy next to the old output transformer. It was installed cleanly with lead dress exactly like the original one to avoid any excess noise. You won't hear any difference. The output transformer is original. The preamp tubes are a mix of vintage RCA 6SL7 and the power tubes are older Svetlana Winged C 6L6GC. The speaker is a fabulous and HEAVY Altec 421A. Which gives this amp a super punchy and full low end. The past owner didn't like the aluminum dust cap showing through the cloth so the cap was painted black. The cone is original however. See photos for cosmetics. There is a leftover 1/4" jack in the side of the amp from a previous owner. I left it in case the new owner would like to use it for a second speaker connection or a thru jack. It can easily be removed or plugged if you want. If you just want a temporary plug. Stick a male 1/4" jack in it. New blue handle installed. This amp has been gigged and well used during its life but has been electrically maintained. Its not a show queen but has years of honest weathered mojo. This could be a reliable gigging amp for you as its been for many years already. Includes the original trolley which is super helpful for transporting it from gig to studio and beyond! This will be packed like a tank to ensure its safe arrival. This will require extra care which not all sellers seem to be capable of. I have a track record of strong packaging and know how to make sure your equipment arrives in the same condition it was shipped in. This is not cheap unfortunately. Packing material costs and postage have all increased as well as insurance. This will be insured for its full value. I can ship this ANYWHERE in the world. SAFELY! Local cash pickup also available. Save $$ Please ask questions. I have answers.
