Eleven (11) Raytheon CK 5755 Vacuum Tubes + Pair 6SL7 Adapters


By purchasing from this listing, you acknowledge that you have read and understood this entire listing, including all my terms and conditions, and agree to accept and abide by those terms and conditions.

I am cleaning out some stuff, so I have a group of 11 Raytheon CK 5755 vacuum tubes plus a pair of 6SL7 adapters.

Price for the entire group plus adapters is $75 (exclusive shipping).

Please ask for a shipping quote.

The 5755 is supposed to be the same as 420A. These are often sold on Ebay as 12AX7 and 6SL7 subs (with adapter). I tried the 6SL7 adapters, but it really did not work well in my application. Other than that, I have no experience with the tube or its possible uses.

There are 5 of the clear top type, and 6 of the ones with flashing.

While I have not tested all of these, most appear to be NOS (“new old stock”).

8 of the tubes are in boxes that appear to be original (4 of each type).

Nothwithstanding, for the purposes of this sale all of these tubes should be considered USED.

I can provide additional information or photos on request.


Please note that these tubes are being sold “AS IS, WHERE IS”. There are no returns or refunds under any circumstances UNLESS I have grossly misdescribed what I am selling.

Notwithstanding, I am an honest seller (please check my feedback on EBay, ID=baileyler), and if there are truly any issues with these tubes that were not described and can be verified, then I will work with any buyer on a reasonable solution.

Payment can be via money order/cashier's check/personal check, but all must clear my bank first. Cash is OK for a local transaction.

I also accept Paypal for convenience. IF YOU PAY VIA PAYPAL, HOWEVER, A CONDITION OF YOUR PAYMENT IS THAT YOU EXPRESSLY WAIVE THE RIGHT TO FILE A PAYPAL CLAIM OR CHARGE BACK (but do retain the right to sue me in court should you so desire). While no fee Paypal is preferred, I will cover any Paypal fees.

Shipping in the US will be via USPS Priority Mail unless otherwise requested.

Full insurance, other shipping methods or full shipping cost shipping outside the USA is not included in the price.

Please request a shipping quote in advance.


Shipping terms are EXW shipping service (INCOTERMS 2010). In accordance with these terms, I will deliver the lot into the possession of the shipping service, and once in the possession of the shipping service ALL RISK OF LOSS PASSES TO THE BUYER.

I only describe what I know about the tubes, so please feel free to ask questions in advance of purchase.
