[TechAssist] Re: Philiips/Magnavox Ch 27D100-7570 Sams 4165

John,
Model TP2781C101 uses a 27D7 chassis, not 27D1. Ref# 3917 in the D7 chassis
is a 10K resistor and ref# 7620 is a BU2508AF.

Model # TP2781C101 Philips/Magnavox

The reason for this post is over the years (35) have found Sams to be
incorrect on many items.   In this schematic they list a Q7620 BU2508AF
substitute as ECG2353 whitch has a built in diode (wrong again)

Thanks for your time
John
