[Hammarlund] SP 600 RF Deck to T1 Wiring Locations

[David Wise]

Beware that Issue 4 is messed up.  The pictorial and the schematic are
from different versions of the radio.  See the Issue 4 Supplement for
the correct pictorial.

Regards,
Dave Wise

Issue 4 and Issue 6 of the sp-600 manuals have very complete wiring diagrams in the back.
You can download the manuals from James (Andy) Moore's website when it is back on line.
 (I just tried it and it wasn't up).

There is a wiring diagram of the RF deck which shows how the RF deck wires go to the E13 terminal strip.
L31 (the left hand inductor in T1 is pretty straight forward, the wires go to T2 terminals 1 & 8
L32 is a little trickier as there are a couple of versions of the V7 circuit, one has a dc ground the other has an
  AC ground.  James' Issue 4 pdf file shows the two variants.

A word of caution, there is one variant of the RF deck where the roles of the red-white and red-green
wires are reversed. Is is a good idea to buzz out the leads of the RF deck to the tubes in the RF deck
to ensure you know which wire is going where.

Hello Group

I am nearing the end of recapping my SP600 Rf Deck and being done.  A big problem I have happened is the wire Bindle exiting the RF deck to the mixer solder points (T!) 7 points I have no idea what attaches to where on the T1 points.

More confusing is someone replaced  these wires so color code wires are moot.  If someone on the list is very familiar with what connection points of the RF wires to the (T1) points would be most helpful.

I have a rough drawing of T1 points on pdf so if you can help contact me off list and I'll attach the .pdf drawing.    wmarvin at hickorytech.net<mailto:wmarvin at hickorytech.net>
