Welcome to Vacuum Tube Depot llc! We have been one of the leading online suppliers of vacuum tubes for many years. Recently, we acquired a very large collection of tubes that we are excited to offer. We have tested and sold thousands of these tubes, and have many, many more to sell. After testing literally thousands of tubes from this collection, we have found only a small handful that did not test well. The vast majority tested strong. Buy with confidence, and if you are not happy with your purchase, you can send it back on your dime for a refund. We will combine shipping on multiple purchases within 5 days of the first auction ending. Payment must be made within 5 days or your purchase will be canceled and re-listed. We do not have the space to hold onto auctions for you for any longer than this. If you would like combined shipping, please wait to make payment until after we have sent your invoice. We send invoices each day after all auctions have ended for that day. Combined shipping can only be combined with this shop, not other shops with similar names. Thank you for shopping with Vacuum Tube Depot llc!

You are bidding on an old RCA MI-12211 25 Watt Tube Amplifier Chassis. The original owner gutted this amp and built it into a complex regulated high voltage power supply. That build was poorly made and extremely dangerous so I tore everything out except for the PT and choke. I believe those are original RCA amp parts but I cannot guarantee it. So you get what you see. Its a project chassis. Build it into what you want. There is a PT and a choke and everything else you see. There is no OT as shown. Buy this for the project platform. Or if you only want the cool tube cage, then I guess recycle everything you dont want. The chassis with the cage measures: 14.5 wide, 8 deep, and 10 tall total. The cage alone is 6-5/8 tall. I have the schematic and instruction manual that I can provide with the amp. Sold as-shown. No returns. No Refunds. HD 16x12x12

Very hard to find RCA 542A. This was designed as a 100% direct replacement for a Western Electric 242A. This is 100% equivalent to the standard type 211. Tested on Amplitrex AT1000. Test: 133mA New value is 100mA It did work in an amplifier. Most type 211 that you see on eBay are untested but this one is fully tested,so you know what youre getting. Selling some of my rare personal use tubes this week. See our other auctions for many more tube lots.
