[ARC5] Why "Noodling" About Sweep Tubes

[Robert Eleazer]

Dave:

I have a 12DQ6B, acquired for reasons that currently escape me.  Looks like it is NOS NIB.  Maybe I bought it in a lot of tubes, not sure.  I am pretty sure the 6DQ6B is a widely used sweep tube.  You are welcome to the 12DQ6B if you wish.

I also have a couple of 6GE5's.  I believe these are sweep tubes and I know I acquired these for use in some future project; I think either a crystal controlled Galaxy transceiver or an HW-18.  I recall they were pretty cheap.

Also, I recently bought a sleeve of five 6883B's.  They are 12 Volt 6146B's.  I plan to use them in a TS-520 I am repairing and also possibly in a HW-100.  They appear to be NOS NIB and cost me a total of $20 plus shipping, a total of less than $30.  Don't know if they are adaptable for the BC-375 but they are available on ebay, occasionally for astonishingly low prices.  The 6159, the 24 volt 6146, is available also; I got a pair for $10.
