I don't know the seller, but he's selling here on the Gon a pair and a quad of Siemens E88cc. The quad is relabeled CBS, but they look like the real McCoy to me.

Siemens made E88CC tubes and labeled them for CBS, so these are likely Siemens tubes, but they are not CCa (and I'm not suggesting the seller is representing them as such...just wanted to be certain to differentiate that they are E88CC and not CCa).

Agreed. Most everyone knows that although Siemens made the E88cc and cca identically, the cca were specially selected for the post office back then.

Hi guys,
Mark here,visit the Canadian equivalent of audiogon.www.canuckaudio.com.Last week there was a trio of CCa's for $225.Also,ECC88 gold pins and Amperex come up from time to time.If you see something you like let me know and I'll ship them to you from my MI address.

Markwatkiss thanks for the link i' ve been tempted to try the Amperex ECC88s with 2.1 i have 2 VALVO Hamburg PCC88 7DJ8 - Single Tubes MINT NOS 1959-60 Hamburg Production and 2 Telefunken PCC88 7DJ8 - MINT NOS 1960s Bundeswehr Falcon Logo Diamond Bottom - Germany to audition looking forward to hearing the differences.

now that ive tried the above tubes and volvo/amperex e188cc along with my 64 ccas and others no doubt they all have there own character and sound. the ccas are more thin sounding compared to the e188s while the amperex have better bass and mids IMO. in the end i believe until you audition a verity of tubes in AHs preamps you may be missing sound that appeals to you better. like finger prints and ears we are all different and what sounds better to me may sound like crap to you. i'm sure most of you have taken the time to experiment on your own and already know its worth the trouble and expense for better sound.
