Hi all. I'm a newbie on here.
I've been given a tweaker 88. Where the customer has tried to muck about with it himself
I have the diagram and have wired it as per the diagram , but something isn't right .
First off does anyone have pictures of there tweaker 88? Or any info on the transformer?
It was leading me to short circuit tx. With excess current draw , But disconnect HT it's OK
So I suspected 1n5408 . Checked and changed them along with c22 -c15. Still have excess current draw .. lifted the ceramic and disc caps. Still I have it
Tested with a known working transformer, just using the HT and ct . Still have the same issue .
QC19 is the ground and the there's a short black wire coming from secondary side . Which is connected to QC19 as far as I can make out.
Gone over the board, can't find a short on anything .
If the tx has a short It will draw excess current with nothing connected
According to customer it was blowing mains fuse in the iec before he took it apart.
Is there something I'm missing here?
Thanks in advance. Hornet lover
