made at Philips Heerlen Holand factory in October 1967
E180CC tubes are probably the best version of 12AT7 with higher quality and lower microphonic
tubes have 1,2 inch longer bottle than 12AT7 tubes
these are 10000 hours longlife tubes box grey plates, O-getter
Great audio tubes - very musical and smooth to listen to
perfectly balanced tube
Ia = 11,0/11,0mA code IV3⊿7J1
where 100% for the new tube is 11mA
you will get the tube you can see at the pictures
very nice sounding 12AT7 family tube at affordable price
I always send the tubes by priority registered mail with tracking number within hours after receiving payment
