Read the following info page (at least, to 3/4 of the way down), from Tubemuseum. The iteration is variously referred to, as solid halo, solid getter, disc, etc., though- I have no doubt; it’s been called other things. https://www.tubemuseum.org/ProductDetails.asp?ProductCode=SH_E88CC_1958 There are pics on that page, but the getter is virtually invisible.
Difference in sound between Siemens e88cc and e188cc?
Interested in user experience with the Siemens e88cc and e188cc. In my rig the Siemens e88cc offers great detail, clarity, imaging, nauturalness and dynamics, but is far less tonally saturated than the Amperex e88cc. Is the Siemens e188cc (forget CCa -- $) better in that regard? How do the Siemens e88cc and e188cc differ in sound?

What audition__audio said, +1. I found the Siemens tubes, made after the early 60’s (silver shield / internal date code), to be brighter (bordering on stridency), in my system. To me; the absolute star of the Siemens 6922 line up, has to be the 1958, exterior and painted-on date code, solid-disc-getter, E88CC. Same wonderful clarity / detail / transparency, as the early 60’s, ECC88 / E188CC / CCa, with the grey shields and external, acid-etched date code, but- even better (more extended) bottom. |
