If they're grey plates and shields, they're early 60's. If silver they're late 60's/ 70's.
Any chance of posting a pic?
Ah cool, hows the sound compared to the 60`s e88cc Mitcham`s, got 2 sets of early 66 and a set of blackburn mullard ecc88 67.
I think Brent Jesse is might selling the same tubes for $325. His description were 70`s e188cc Mullards with the RTC logo
Looking at a set of Seimens e188cc grey shields, date code is G0/1F/4A. Anybody know the year of production?
