That photo looks eerily like my own workplace, a few hours from now.
My chassis was finally evicted from Charles de Gaulle, and is now making its way through the US.
Don't forget when soldering in your front-end JFETs to leave the leads on the long side for easy de-soldering and recovery later. Best to do what you can to preserve these rare creatures in case you wish to re-use them, such as on a new front-end design. Or, you could socket them with machined pin sockets (which is what I will probably do).

Any progress update ? How much is heatsinks temperature after 1 hour ?
Hot or very hot ?
BTW thermal paste included in the kit that is "take great care of the details"
I´m interested too, but, well, approx 60 Watt for 30cm x 17cm heatsink should be ok..
Do you mean I wasn’t supposed to peel them off?
Put a coat of clear nail polish over it.
Soldering tips from a Pace HiRel course taken long ago. Clean pads and leads with lint free wipes and 99% Isopropyl,never use erasers etc. Flux all joints "flux is your friend".Solder tip about 650F,use SN63/37 eutectic solder (this was long ago but lead free is a pain in the As#).Clean residue with Isopropyl (acid brush works good).
My iron is typically set to 666 deg F, because my amps will play a lot of metal when done!
Parts kit is in transit, and should arrive tomorrow. What a week coming up - vfet & 2nd Covid shot!
