For Sale / price drop:  LEAK STEREO 50 amp - 1958 date code. Fully restored by Stereo Rehab in Chicago. See description of the work (in the last photo). See the bottom-view photos for the restoration work. Check the reputation of Stereo Rehab. Components on top plate left in place for originality. Sold without tubes, other than the JJ rectifier, if desired. This amp deserves your favorite 12AX7 and EL34 tubes. Price: $1190 + shipping. If you feel like that is high, let's discuss. 

There is some oxidation and marks on the transformer tops. See photos for details of condition of amp. The mentioned warranty has expired, and this is sold without warranty, as per usual with used vintage equipment. The banana adapters shown in the photos are a free bonus and come off if the original screw terminals are preferred (they are a bit loose at the moment, but can be tightened).

Quotes about ST-50s:

“Those amps just drip classic, and they are built beautifully, as well. They fetch very high prices from the fetishists. With those, I would urge originality if there is any way.”

“They say the secret to [the vintage Leak] amps are the transformers, all beautifully English made and an art that's been long lost, except for some Japanese exotic transformer winders like Tango or Canadian Plitron.”

TUBES:  Buyer should add premium tubes to taste.   A few tubes can be included with the sale as extras.

CONDITION:  5. Vintage amp in fairly good vintage condition.  Oxidation on transformer tops.  Lots of little marks - but looks good for its age imho.  See photos.  Operates and sounds great.

SHIPPING: Flat Rate ground shipping $65.  Will be solidly packaged.
