ps Don't for get the paper caps inside the IF cans HaHa.

Do you mean in the SP-600?  Oh yeah I got those.  I had two that were pretty much dead shorts that brought the B+ down and took a couple of resistors with them.  Those were a piece of cake to replace.  Now the RF deck was another story.  This one had mice in it at one time.  The RF deck was so corroded I had to replace 3 of the 4 tube sockets and the antenna connector.  I had to take a butane torch to a few of the screws to get them loose.  Also had to repair the hexagonal shaft in the turret assembly because it broke.  This was an early SP-600 JX model.  The other one is a JX21 in much nicer condition.

My HRO-M also has the shouldered tubes (although 6V versions) but it has the square IF cans.  I would have preferred the table top amateur version but this one was local.
