Philips 17" BW tube set
Hi to all.
I am from Portugal and I like to collect and repair old radio and TV sets. i just purchased this amazing Philips 17 inches set from a local advertisement for only 60€. I replaced the tar capacitors (across the line and boost capacitor) also replaced the capacitor from the Pl36 heater to ground wich normally fails. It had a broken wire on the CRT socket and a bad power switch. After those repairs it is working with a very nice picture and all original components and valves. |

Re: Philips 17" BW tube set
Well done. Is that a 1768 or something similar. Those black capacitors are generally fairly reliable but changing them certainly wont hurt.

Re: Philips 17" BW tube set
HI
it'a 17tx291a i also have a similar model with a 21" screen they work beautifully the philips black tar capacitors from my experience on philips devices are always deformed/melted and badly leaky , i have one here in the bench 0,022uf at 10000v which lets 71volts dc pass through when applied to it a voltage of only 100vdc...so its almost shorted... but the yellow "mustard" capacitors and the tropical fish ones in philips sets i never found a single bad one.. electrolytics are also very reliable.. the 21" set i have restuffed them for precaution but on this 17" they are the original ones. here are some pics of the 21" set, i also paid 60€ for it but the lady wanted more, i had to convince her to do that price. i have lots of great german sets i would like to share their stories and some hours of footage of capacitor restuffing, repairs etc but the other forums i tried seem to be quite empty and few people are there. Here in Portugal the vintage tv and radio community is non existant virtually. |

Re: Philips 17" BW tube set
Great result. The rounded corners suggest it is a 110 degree tube. Maybe a variant on the UK 17TG100U. Any chance of some internal pictures? John.
