70GS-64S ALTERNATIVE PARTS 1. CRT THOMSON: VB66EHJ4312*N or VB66EHJ1312*N. The original Philips CRT (VB66EAK0714*N) may be replaced by VB66EHJ4312*N or VB66EHJ1312*N depending on the stock of CRTs. Both Thomson CRTs are completely interchangeable (VB66EHJ4312*N has got a glass transmission (GT) of 48%, while VB66EHJ1312*N has got a GT of 52%). In case you receive any TV with one of the above Thomson CRTs it may perfectly be serviced thru Schematic Diagrams included in this Service Manual, the differences (in most cases of value) are below detailed.
