On a related matter, the  heat sink of the IRF 510 on this tcvr and also on the uBitx  is live to ground ( It's a feature !!) Bear that in mind when working on it or casing it.  The Fuse on the supply line is good but it is likely the IRF will be destroyed first if the heat sink touches ground (current will flow  from the PSU to the Drain , out the tab on the case ,the Heat sink and to GND).
