To reply to a number of questions received I temporarily pulled the sale to revise the listing with more information. I've now relisted. Here are replies to some questions I've received:I purchased the amp in December, 2016, from a private party here on eBay who had listed it as "New, Not Refurbished", yet made no claim to being an authorized Marshall Dealer. I can't be certain of these claims, and don't consider myself to be the original owner since new, so I didn't try to register it as new on the Marshall website.I had some work done on the amp by a Marshall Factory Authorized Repair tech when the output became intermittent. The tech discovered an intermittent in the output transformer that had probably been there since factory new. He repaired the intermittent and gave the whole thing a clean bill of health. I paid fot this repair out of pocket. I speculate that the person I bought it from ran into this intermittent and for whatever reason decided to sell the amp rather than have a Marshall Authorized Tech repair it under warranty. The tech I brought it to also rebiased the amp for the new Tung Sol EL34s I installed. These tubes probably have less than twenty hours on them. The original tubes, he thought, had some useful life left in them so I kept them as backup.The serial number is M-2011-38-0587-2I can double-box upon request, but this will probably raise the shipping costs - it's already very heavy.Packing includes all molded expanded foam inserts, reinforcing cardboard corner strips, etc. The packing will be as solid as I can make it. I pack the way I'd like to see an item upon receipt (and believe me, I've received a few disasters where I couldn't believe someone would ship that way...). I'm hesitant to see this amp shipped across any more oceans - if you're outside the North American continent, please consider very carefully whether you want this amp shipped that far.
The terms of this sale are As-Is, No Returns. The amp is very robust, but tubes are liable to damage and aging. Please buy knowing that you'll have to re-tube at some point, that proper bias matters, and that the day will almost certainly come when you have to let an expert work on this amp. That's simply part of tube amp ownership. The good news is that any decent amp tech will welcome the opportunity to work on this amp, as it has a very high level of integrity in its design and construction - all hand wired, readily serviceable, no printed circuit boards with fragile traces! Properly maintained, this is an amp for the ages.I'm selling only because I've concluded that, while amazing and awesome, this amp does not represent the highest level of practicality for my recording needs. I'm really glad to have worked with it, but feel it ought to be in the hands of someone who will give it regular use. Compared to my purchase price in December, I'm taking a beating on the price of this amp! It's priced low mostly to move it, but also to reflect the fact that while gorgeous, it's not factory new, is not under warranty, and has needed some work. I've described everything I know about this amp and rely upon the buyer to assume the risk and make their decision accordingly.
