I was planning to DIY this CRT rejuvinator , it was for sale as KIT from italian
magazine , they now close theyr business from years and that kit no longer
available from years too. The main problem its the T2 transformer they never
reveal the specification so its hard to guess , they called it in the article
modulation transformer , labeled TM1298.
At pin 12-13 of IC1 SG3524 we have 80khz squarewave thats driving mosfet MFT1
with DS1,Z1 and C13 forming an switching psu with an output beetween 8v and 20v
regulated by R15 used to modify the amplitude of squarewave , pin 3 signal
goes to TR3 that invert and drive IC2 that divi de by 2 circa 40khz this signal
this signal drive the half bridge IC4 and then this last one driving MFT2 and MFT3
connected to the primary of T2 at the secondary we get 400Vpp filter by C16-C17
and Z2 making it sinusoidal better as possible.
So hopefully someone can help me to identify and find an adequate transfomer
to replace it.
