Ha-Jo & Peter,
Thank you guys for the information on the transistors. I have noted it in
my logs These are very old transistors with lots of gold plating!!!
Thank you,
Mike

for transistors...
Dear Mike,
in an old RCA Transistor Manual, Technical
Series SC-13, the 2N1309 is listed as:
Ge p-n-p alloy-junction type
used in medium-speed switching applications in data processing equipment. The
2N1309 is the p-n-p complement of the n-p-n type 2N1308.
Jedec TO-5
Outline Nr 3. Terminals 1 - emitter, 2 - base and case (!), 3 - collector.
This type is identical with the type 2N1303 except the following
items:
VCE sat (IB = -0.13 mA, IC = -0.5 mA) -0.2 V max
VBE (IB =
-0.5 mA, IC = -10 mA) -0.15 to -0.35 V
Collector to emitter Reach-Through
Voltage Vrt -15 V min
Static Forward Current Transfer Ratio:
VCE = -1 V,
IC = -10 mA hfe 80 min
VCE = -0.35 V IC = 200 mA hfe = 20 min
Small
Signal Forward Current Transfer Ratio
Cutoff Frequency VCB = -5 V, IE = 1
mA fhfb 15 MHz

--------------------------------------------------------
The 2N508
is not in this Manual, has obviously been manufactured by another
company.
OK?
