Up for sale is a matched pair of the famous Siemens CCa tubes.
Both are NOS, and test very strong:
Tube 1: 17.7/18.5 mA, amp. factor: 15.5/15 ma/V
Tube 2: 19/18.5 mA, amp. factor: 15.5/15 ma/V
Physically perfect! They come in white boxes.

USD $270 + $15 air mail shipping. Will pack well!
E-mail to whistler[at]pageone.no for more info!

Yes, they are. :)
Please, note the slight difference between the letters on the two tubes. (Refer to the picture). That could mean that they come from two different production runs, however, they should be closely matched. (I am a DIYer, and not a tube collector.)

The tubes come from a large collection of CCA tubes that was salvaged from telecom equipment that was never put into operation, because of the advent of the transistor.
