[volt-nuts] Tektronix TM500 extender cable kit

[Mark Wendt]

John Griessen on the Tek list also sells extenders for both the TM50x and
the 7000 series of scopes.  I have both sets from him.  His are a little
more expensive than $20 a kit, but he includes the pre-cut and twisted
wires and the connectors.

Here's an image of his 7000 extender, soldered up:

No connection with John's business, just a happy customer.
