Please look at pictures for details. Shipping costs are calculated by bidders location USPS tracking is included. PLEASE READ: I buy several items at Estate Sales and Auctions. I do not always know what goes with the items I sell, or how they are supposed to look. Under the same conditions I buy items, the winning bidder gets the items as found. I do my best to describe the items how I see them, and I am bound to miss something, so ask if there are any questions. The pictures should speak for themselves. All sales are final. If you are not sure what you are looking at or are not comfortable bidding, please pass. I do expect payment within 7 days, but will work with you if other arrangements are needed. If payment is not received within that time, you will be reported.

Rare and original Beard CA35 Valve Preamplifier User Manual. Generally in good condition but some minor damage on each page which does not affect the legibility of the text or the usefulness of the document (see last two photos).
