Hi

I just realized that this thread is one year old!

Btw, I am on medical leave since I had a tooth surgery today. Keeping ice on my face as I browse. Otherwise, not bad, I took some days of medical leave and just started looking around for my toolbox...

Rob,

Can you re-post some close-up pictures? The devil is in the detail

everything seems fine ( at least to my tired eyes ) , except awful soldering ;

you probably fried that poor mosfet .... or you have short between that isolated wire and one underneath

Hi guys,

Just a few quick question on the raw power supply of the original delite including the lux version,

1) will it somehow damage the Jfet (SJDP120R085) in a long run due to on/off surge voltage/ current that occurs? A ZenV9 alike circuitry (replacement of the light bulbs with the supply filter and the constant current source.) helps in this scenario?

2) Will it be worse for the Jfet if one is to install a delay turn on relay circuit at the speaker output?

Reason for the above questions is that the Jfet (SJDP120R085) ( seems to be pretty venerable, burns out too easily although heatsink and stablised voltage is within acceptable range (< 85vdc & < 65degC). Upon startup, a few seconds surge @ 79V at output capacitor is seen too.
