A New Hope... "I knew you could do it!"
Ninten-doh:
Perfect! Thank you so much. :applaud:
RetroACTIVE:
I've stared to do the amplifone rebuild ... here is the HV board... Now I'm not going to take credit for the resistor mod... Level42 gave me the idea... so I'm simply riding his coat tails...
These are TO220 power resistors... 30W 50 Ohm. You can see in the pic how badly burned the board was from the old mod... We'll see how it works...
Here is the solder side ... everything re-flowed...some bad pads had to be dealt with on the regulators. I also added some heavy guage on the one trace that was pretty much cooked off the board from the old resistor heat!
New flyback... and all cleaned up ready to go...
I"ve the deflection board about finished...
ChadTower:
Nice job. I usually jump those traces with wire rather than risk heating the trace and delaminating it even more. I seem to see that more on much smaller traces, though. What you did looks pretty nice!
Level42:
Wish I had seen those TO220 resistors before I did my mod !!!! Looks sweet ! 30W seems an awful lot of power for such a tiny package, I guess it really depends on the used heat-sink what the real wattage is. At least it is well over the 5W that Atari used.
I hope the heat will go into the heat-sink mostly, as the only doubt I have about this set-up is that the TO-220's are pretty close to the caps.....
No other way then to try it I guess :)

@Spy - Do you have a link to the TO220 resistors? Or some extras for sale? I'd like to pick up 4 for my 2 HV PCBs...
Thanks!
