Only the spare part described in this advertisement is on offer, not the complete equipment
The Philips PM series of professional video test pattern generators were "stock in trade" for the professional television serviceman from many years ago.
I like to restore dated equipment where possible but too many things were wrong with this pattern generator so it is now being "parted out" - both of the interlocking switches were faulty and some of the preset channel knobs had gone missing.
Prior to dismantling, this equipment was fully functional (although difficult to use with the cosmetic issues it had!) so I decided to "part it" instead of restoration.
Philips Colour TV Pattern Generator
Model: PM 5519
SPARE PART ONLY, AS DESCRIBED BELOW
Complete main printed circuit board with plug in modules
All components you can see in the photographs are included. I had in mind that this main board (or the modules) could be useful as a source of "difficult to find" spare parts.
NOTE: Although fully functioning electronically, two of the interlocking switch banks were not operating correctly (not locking) and I was not about to source and fit new switch banks - so this is NOT offered as a drop-in replacement main board.
Some of the active components are extremely difficult to locate these days.
Some interesting devices on the board are:
OM320 - Hybrid IC amplifier for VHF-UHF
OQ5501 - Pulse Generator
OQ5502 - PLL Master Oscillator/Sub-carrier Oscillator
CA3086 - Silicon NPN Transistor Array
TCA420 - IF Amplifier with symetrical FM demodulator
Diodes - BB106, BAW62,AAZ15
Transistors - BF494, AF367, BF967
Plug in modules:
Unit 1 - 5322 212 84113 (Master Oscillator)
Unit 2 - 5322 212 84115 (Sound Oscillator/Sound Modulator)
Unit 3 - 5322 212 84116 (Multi-burst Oscillator)
The rest of the active and passive components are very stock standard, digital IC's are almost totally 74LS series
Since removal from the equipment, this printed circuit board and the modules are now stored in a sealed ESD bag.
