The other day Larry brought up the subject of the GS-35B tube. Just prior
to his posting I offered up a late date coded fully tested full output
3CPX1500A7 with my usual guarantee of satisfaction to the buyer. I got no
takers
for the 3CPX1500A7 as of yet, but I told Larry and the others here that I had
a NIB GS-35B I wanted to sell. Offered it up for $85.00. Larry promptly
grabbed it in a heartbeat with a private e-mail to me. Within in 10 minutes
to
Larry's swift decision, 3 more offers to buy the tube came to me.
Unfortunately I do not have 3 more of those tubes. Sorry guys. So while we
are at it,
I'd like to go over my experience with these 2 tubes. I built a 6 meter
mono band amp from an Ameritron AL-82 platform. I wanted to try the GS-35B.
I
read somewhere that this tube was nick named "the poor mans 8877" So for
$100.00 each I bought 3 of them. Back to the 6 meter Ameritron, fabricated a
sub-chassis arraignment to mount the GS-35B neatly in the Ameritron space
available. All went well with about 1/2" to spare at the top before hitting
the
top cover. Had to add mucho additional bias voltage, no problem though. Get
everything working nice nice. Being a stubborn Italian, I no stoppa til I
getta ever bitta a powah outputta. My Granma always said "we don't wasteta
notting"!! Well after chocking the chicken after it's been dead, I ended up
with 1600 watts output with 100 watts drive. No mas No way. Hey not bad,
1600w on 6 meters. Previous to this, I did a similar job, but using an 8877
in
the place of the pair of 3-500's. Same scenario, mono band 6 meter. This
time all things being equal, I get 2300 watts output. Ok, so the 8877 costs
about $300.00 more than the GS-35B but I get 700 watts more, that's 50 cents
a
watt. Grandma says that's cheap so I go with 8877's now. Buon Giorno
Tutti. Luigi
