[R-390] misc posts

[Perry Sandeen]

Yo Bubba Dudes!,
The mounting screws are 10-32 for the R39X and SP 600.  Others are either 8-32 or 6-32.  IIRC the tube socket screws are 4-40 are are those in the SP 600. I buy them in SS from McMaster-Carr by boxes of 100.  They have every type of screw head one wants. SS is very little more than plated steel.  They look great and won't every fade or rust.
Wanting a R 389.  I wanted one years ago but i didn't have enough grandchildren to sell.  I also realized that using, maintaining and repairing it was far moe work than I ever wanted to get into.
The R725.  If it's a ladies radio get me a dress and some lipstick. (As I live in CA no one would bat an eye - even if I grew a beard with my new outfit.   It doesn't have the ringing of the mechanical filters.  If you can score a Non-A IF [a difficult feat in of itself] Tom Marcotte (sp) wrote a step by step article to be able to add it to your *A* that's in the Y2KR3 manual.  Or if one comes up for sale on ebay, pay the price -you can cry about it later- and enjoy.

But if you want to be a real Caveman man and suffer the OEM crappy audio - go for it. We don't discriminate against masochists on the list.

Well, first you have to find one to buy. Then see if your credit card can take the hit.

Then, You'll have the heat to deal with. There is an expensive to maintain, complicated regulated PS.  Less commonly used IF tubes which are in a series circuit, large leaking oil caps, almost impossible to find spare parts for starters......so go for it Bubba.  It'll keep you out of gin mills in the winter time. 


 But there is the nice sounding LC IF and the potential for a good audio and other upgrades. Also the issue of getting nice clean large ski's... 


So put on you're Fred Flintstone outfit grab a club and charge!


Of course as our most respected senior: senior member Les Locklear would add: YMMV
