Heath SW-717 SWL Receiver For Sale:

The SW-717 is an SWL receiver.  It is typical of an SW receiver; if 
you are looking for extremely good quality and performance, then this 
one is not it.

Info from the web:

The SW-717 is Heathkit's solid state successor to a series of receiver 
kits that started with the AR-2 followed by the AR-3 and then the 
GR-91 and the GR-64. All of these were single conversion tube-based 
superhet shortwave sets covering 550 KHz to 30 MHz in four bands. 
These were considered entry level shortwave sets, often built by 
teenagers as a first major kit building project and commonly used as a 
first receiver by amateur radio novices. All have a BFO and 
bandspread. The AR-1 was of course the great grand daddy, but it only 
covered three bands and had no BFO or bandspread. (see catalog ad for 
the AR-1 on bottom of page at this link)

The SW-717 was introduced in 1971 and remained available until about 1982.

The color scheme and outward design of the set show the family 
resemblance to the GR-64 and GR-91. Like all of the sets, the SW-717 
is single conversion but replaces the usual 4 or 5 tubes plus 
rectifier of its predecessors with 9 discrete transistors and 11 
diodes. It also has 3 ceramic filters in place of the usual 455 KHz IF 
transformers. Transistors are MPF105 oscillator, 40673 RF amplifier/ 
mixer, 2N5308 Darlington IF amp, two 2N5323A IF amp and AGC amp, 
2N3393 audio preamp, X29A829 audio driver, and MPSU05 and MPSU55 for 
audio output. (S2090 and S2991 for audio output in some versions. 
Other transistors for audio and possibly for IF may also have been 
used during the ten year run of the set.)

The radio has a ferrite rod antenna attached to the cardboard back for 
reception of the broadcast band and the usual terminals for an 
external antenna for the three shortwave bands.

This particular SW-717 works as it should, for what it is. 
Cosmetically, it is extremely good, especially considering its age.

Buy it, with paper work, for only $50.

Resistors for high voltage metering For Sale:

Do you have a linear amplifier that has an
error in the high voltage reading? Maybe you do
not even know it has an error!

Heath used three 4.7 meg resistors in the SB-220/221
and also in the SB-200/201 amplifiers. Almost all
of these resistors are out of tolerance today, partially
because of their age, but also because their voltage
rating was exceeded.

I was able to obtain a quantity of new resistors that
are 4.7 Meg, 1% tolerance, 2 watt, and are rated to
handle the high voltage. This compares to the original
resistors furnished by Heath that were 4.7 Meg, 5%,
1 watt and about 400 volts.

Note that these can be used in any amp that uses the
4.7 Meg resistors -- not just Heath amps.

Buy a set of three for $3 plus shipping from Florida.
Combine with other items to save shipping!

I also have a few 0.82 ohm and 1 ohm precision
resistors, as used by the SB-220/200, available.
