Ave Tanyalakók!
Tegnap szert sikerült tennem egy Fok-Gyem TR-9253/A tápegységre. Belülről elég eredeti állapotban van csupán pár kondenzátor lett benne cserélve a gyártása óta. Az itt fent lévő TR-9253 rajzzal köszönő viszonyvan sincsen!! A hibáját 5 perc alatt sikerült orvosolnom :) . De a tartós zárlat már két tranzisztort megölt (2n3773)! Egy-két dolgot furcsállok a gépezetben:
1: 1db 2N3055-tel van megoldva a szabályozás
2: A Graetz-et alkotó diódák minimális hűtéssel КД202Б (KD202B) Kolya kedvéért, hátha így be tudja azonosítani :)
3: КД202Б dióda sorban a kimenő árammal
4: Nem akarnám lerajzolni, de a szükség nagy úr :)
Éppen a tárgybéli szkópomat kellett javítanom. Ez már készen van, de megkérdezem, mit érdemes cserélni benne? Elkókat? Esetleg más szokott bizonytalanná válni?
Gondolom bármilyen más EMG szkóppal kapcsolatos hasonló tapasztalat jól jöhet.
Köszönöm.

Hi guys,
I've obtained bare Wavetek 1175 Benchmark scalar analyzer without any probe and manual.
The problem was in power supply, now is ok, and problems persist without probes ( for Ch A and Ch B) and manual.
Wavetek description for probe is: Power sensor with dual balanced, zero bias, low barrier schottky diodes.
I cannot find original probes, but I will make probe, I have some experience with GHz milivoltmeter probes (HP3406A , TF2603 Marconi).
System have message : Absent probe, and probes is detected with 3 pins of microcontroller 87c196 on AD board.
I need service manual or the schematic diagram for original Wavetek probe.
Any help and advice is welcome.

Sziasztok
Szeretném felújítani a fenti remek kis műszerem.
Az elektronikát megjavítottam, de sajnos a skála felirat lekopott az olvashatatlanságig.
Ha valaki megtenné, hogy lefényképezi és elküldené nekem, nagyon örülnék.
Köszi
Szabi
