    Description

    Working on cleaning out shop.
    I have accumulated tons of electronic equipment and amps over the years. My goal was to restore and rebuild them after I retired from my real job. I opened a tube amp restoration business and it has become quite apparent that I will never get to my own stuff.
    This is a very heavy power transformer for tube amp construction I can't remember what I bought them for but it is time for them to find a new home. They are approx 4 X 5 X 3 1/2 inches and weigh approx 11 lbs a piece(you can buy one or both.
    Here are the specs as I have them -
    2 sets of primaries both 120 V AC so it can be wire for either 120 or 240 volts.
    Secondaries include;
    -330 V secondary at 225ma You will need to use a full wave bridge or voltage doubler as there is no centertap on the HV secondary
    -6.3 volts CT at 6 amps
    -6.3 volts I would guess around 2 amps
    -6.8 volts at about the same
    - 44 volt winding for bias supply- if you need more than that you can use a voltage doubler.
    Shipping is .95 via USPS Priority Mail with DC in Continental US. Shipping is the same if you buy one or both. I will probably bolt them to plywood in the box to make sure they don't shift.
    I have been an electronic hobbyist for over 45 years. I write articles, for AudioXpress concerning restoration, repair and maintenance of vintage audio equipment and radios.
    I build custom audio amplifiers and speakers for customers, as well as for pleasure.
    My interest is in preserving and promoting the use of many vintage items. I offer a restoration service for select audio brands including Heahtkit, Dynaco and McIntosh tube amplifiers.
    I also collect and restore Bulova Accutron watches from the 60’s and 70’s and Zenith TransOceanic Radios from the 50’s and 60’s.

    Shipping
    I will ship as soon as I can after your payment. I use USPS Priority Mail with Delivery confirmation for small items, and Federal Express Home Delivery for larger items.
    FED EX CUSTOMERS, IMPORTANT
    : please add your PHONE NUMBER to your note in PayPal, as Fed EX requires this for all shipments
    . Please note that if you pay on a Friday evening, I CAN NOT ship FED EX until MONDAY AM.
    I want your item to reach you in great shape. I do NOT PROFIT from my shipping charges. Packing delicate items for survival is an art; it is time consuming and expensive. I charge only for the cost of the materials plus the actual shipping company costs. As examples, new boxes cost between -25 and a large roll of bubble wrap costs . Because all the major shipping companies will deny claims for items shipped in used boxes, I use new boxes for expensive and heavy equipment. I also double box any item that has tubes or glass, or is particularly fragile. This adds to the cost, but helps make sure your item arrives to you in the SAME CONDITION it was shipped. Proof of careful packing also facilitates any damage claims. (See below in FEEDBACK for general instructions on what to do if damage occurs during shipping.)
    If you choose to ship by FED EX, and provided PayPal with a valid email address, you will receive tracking information from FED EX when your item ships, and communications regarding any issues they run into.
    OVERSEAS BIDDERS- Because of negative shipping experiences to overseas addresses, I do not ship outside the US
    I leave feedback when you pay for your item. When you receive the item, please unpack it right away, and carefully inspect for damage and function. Please leave positive feedback for me after you have verified this.
    If the item is damaged, it is VERY IMPORTANT you keep ALL the packing materials and boxes until the shipper has inspected them. YOU will need to file a claim with the shipper. In addition, please contact me, since we will need to work together to resolve the claim.
