I'll second that, on both points. I have a Hakko on my bench at work, and I
love it. But it does require a certian technique, and rigorous attention to
care and feeding. They often proclaimed to be a piece of *(&$ by people who
don't understand them. For those who do understand, they work quite we
I have the Hakko and it works very well for PCBs. There is maintenance,
however. You do have to go through a cleaning process.
For chassis work, a good spring loaded pump works just fine.

Hi Jim:
I have a very expensive vacuum pump desoldering tool on my bench but I
find that the best desolder aid for larger terminals like tube sockets
and terminals in the Drakes is braided copper solder wick. I use the
wide stuff..I think it is about 3/16" wide, and it is flux coated so

Good that it was the connector, and not the IC!

Very effective at thru hole as well as the smaller tube circuits. A spring
loaded solder sucker with a gun works well on larger tube items.

I love my HAKKO 808. I've had it about three years or so, and it's hard
to beat for PC board work. I still use a GC "Solder Aid", pointed probe
on one end and slotted pin probe on the other that solder will not stick
to, two or three sizes of "Soder-Wik" braid, and two sizes of

OK. The receiver MUST be in the EXT MUTE, NB or CAL to be muted by the transmitter. If you unplug
the MUTE cable at either end, with the receiver in any of those positions, the receiver should mute.
There should be NO idle current when the relay is de-energized. If you pull V11 does
I have been looking for a good desoldering unit that works. I have looked at

First thing's last here:
In the R-4a, the tube just in front of the power transformer has very poor
connections with its socket. Is there a good method of cleaning the pin holes
in the socket? What does that tube do? It's pretty microphonic when I wiggle
it just right.
Any suggestions, plea
Hi all,
The 80 meter crystal in my R-4C stopped working so I borrowed the one out of my
R-4A. Works fine but now my R-4A needs a crystal.
Noticed five holes in the R-4A chassis just in front of the crystals. Might
there be trimmers under there that could get that crystal working again? Maybe

Make sure that the TRANSCEIVE switch is in SEPARATE and the MODE switch
is in SSB. Are you SURE the relay is dropping out? If these are
correct, pull V11 out of the socket. A heater-cathode short in this
tube will keep the transmitter keyed.
Check the relay carefully. It is possib
