Tubegear
New Head-Fier
I have quickly tried two gold frame grid Telefunken PCC88's. First impression is that these are nice sounding tubes (maybe a bit thin in the bass/lower midrange) but nothing special. I have to give these tubes some more time but I think I like the 1960 Philips E88CC "PTT" better. I still need to try the Tesla's and RFT's as well, should make a nice comparison.
Meanwhile did find some decent testing unicorn tubes in my stash:
Siemens PCC88 with angled D-getters and DJO/≠6K and DJO/≠6L date codes. These codes would date the PCC88's at 1956 and therefore these are likely some of the very first 6DJ8/ECC88/E88CC/PCC88 types ever produced. Strange thing is the Siemens do not have pinched waists. Very limited info online on the DJ0 PCC88's, I do own a 1957 Valvo DJ0 but this does have a PW and normal D-getter. Need some more time on these Siemens PCC88's to form an opinion on the sound.
