check out this Philips set!

Just found this 1979 Philips K12 chassis 26" set on the curb!

This set is unique in that it has a 10 watt @ 0,1 THD amplifier driving a two way speaker system with a long-throw 4" woofer in a large transmission line enclosure, giving a 40-16 khz response within 3 db

Sadly, the K12 chassis is quite unreliable, the edge connector of the E-W plug in module is a big problem and virtually all surviving sets (including mine) had their E-W module hardwired to the chassis at some point in their life, and the thick film RGB cathode driver modules (they used SMD transistors, diodes and capacitors on a ceramic substrate with printed resistors) are another weak spot, when they fail they cause the beam current to scream away until the protection circuit trips and shuts off the set... i needed to replace two RGB modules in my set, also, the memory backup nicad battery tends to leak and damage the memory/control module, but luckily, mine was still fine!

But once fixed, they do have a heck of a sound, and 20AX inline CRTs used in 70s Philips sets are extremely durable and they still produce a sharp, gorgeous picture after 30 years of hard use!
