There are resistors that fit better but I saved a lot of money by getting 100 Xicon's
Yes its a very tight fit
That SMPS looks interesting to me and its current limited to 1050W, would add the fan for sure.
I would like to try it, with two 50v feeding the unreg and with the GRLV set to 40v or slightly lower if using balanced as I don't really need 640 Watts RMS class AB
been wanting to take mine apart and make it into mono blocks that could be used as stereo or balanced and so it wouldn't weigh 80LBS
also need to double the size of heatsinks or add water cooling
And Yes I had trouble on startup with 1000va of transformer feeding close to 200,000uf of caps
the current inrush blew 12 35A diode bridges and the resulting short to ground blew up many of my soft start components
I guess you can use the amps supply at +/-40 and then you don't populate the reg transistors.
But I would go with +/-55v and then use the reg transistors and the GRLV to make the 40v references
you might get away with +/-50v because the voltage drop of the GRLV should be minimal
that way it's going to be absolutely noise free.
congo5 did have some trouble with the power on, the switch on for the transformers he is using drew something like 25 amps
If that smps supply is designed
