I have up for auction an excellent pair of Quad QCII Tube Preamplifiers as shown from the early 1950s. very clean, fully tubed including new tung sol 12ax7, and Mullard EF86 tested as strong on my Hickok 539B. Guaranteed to work well for you with all 3 cords to power and hook up the amps I have for sale in another auction. Shipping is a fixed $30 in the US and $125 international with no reserve price so high bidder wins and you will be pleased. If you win the amps as well, I can combine packages to save you money shipping. Cash on pickup, paypal, certified check are all good.
