Turnip:
Hi Folks,
Have one of these where the FSD200 has done it's usual pop. Looks straight forward enough, but haven't seen this PS B4 - looks better than those former ones with drooling caps.
Anyone done one ? also any thoughts about fitting a safety resistor in the HT to S/by feed - bad for business perhaps.
Chris.

hello again, after fitting these devices i always put a 4.7 zener across the primary side of the opto, it seems to make them last longer, but they do seem to pop for no valid reason
Turnip:
Hi, and thanks Tony,
Glad to note you're somewhat recovered and are back with us - all seemed rather too quiet, the last few weeks, couldn't really argue with anyone, Quuq folks are all so nice to a dribbly pensioner, but what about that posited series fuseable resistor ?
Chris.
PS - Checked out 'Ohm supplies' list and replaced items suggested. Link J300 being the HT feed was replaced with an 800m/a - all seems well.
