Message-ID: <20040201234314.VMVS10514.smtp2.fuse.net@smtp.fuse.net>

Hello Group, have owned an older Hunter Bandit 2000C for some time, second one I owned actually.  It comes with a pair of Amperex 8163, however, Ive been running a single 3-400z in it with no problems, as well as a single 3-500z.  My question, Ive tried running 2 of the 3-400z but get some high resting plate current for some reason. This does not occur with the 8163's and the 3-400z's run by themselves do not run the resting plate high.  So, does anyone know why this would be so?  the current is about 100 ma, maybe a bit less, hard to tell on the meter exactly, causes the plates on the pair of 3-400z to run alittle orangish.  73  Tim K8WBL

Well Bill you bring up some good points.

I inherited this transmitter from a friend.  I am just hoping to keep it
original at least as being vintage is concerned. 

Re the glow, if I got those carbon plates glowing I would be concerned HI!

I suppose when it comes down to it I can always swap out to a more available
tube. Heck, I was even considering 304's or 250's as you mentioned.

The modulators are HF200's, the exciter / doubler is a 807 & HF100. All in a
fully packed 7ft rack.

Maybe a pair of 250's modulating a pair of 250's is not a bad idea.

I don't know how many years the transmitter has sat idle but I will get it
going sometime soon.  Hey, its been around since about 1937- a couple more
years will be insignificant!

Is a burn in time needed on a new  3-500?


What is the recommend procedure on a new tube?

>Is a burn in time needed on a new  3-500?

>From the RF Parts web page:

TUBE BURN IN
Transmitting tubes generally require a "burn in" time to increase emission
to its nominal value. In broadcast stations, 100-200 hours at rated filament
voltage is allowed for burn in. This initial operation allows the getters,
materials which absorb and hold residual gas, to finish the vacuum of the
tube in its final operating environment. In an Amateur Radio amplifier,
tubes will often require 50-200 hours of "key down" transmit time to remove
the residual gas and condition the filament for full emission. It is well
advised to allow tubes to operate in standby mode (filaments on, no
transmit) for 10 hours before tune-up.

The 811A, 572B, 3-500Z, 4-400, etc. utilize a thoriated tungsten filament,
which is highly dependent upon sufficient filament temperature to provide
adequate electron emission for normal operation. Emission increases as the
thorium migrates towards the surface of the filament wire. This is why it is
recommended to "burn in" these tubes before operation

Hello there,

A bit off-topic, but I have number of used russian FM transceivers "Lion" 
for sale.
They working around 50MHz band and could be modified to 6 meters beacons - 
one now is working as LY0SIX at 50.064MHz. All equipment is used and 
uninstalled from the cars (was used in the Ambulance, Gas Service, Power 
service and so on at the State services). Quality is different but I hope 
most of them are in working condition. Shipping price is not known yet, 
but is somebody is interested in - I will weight the equipment and will 
calculate actual shipping price (I hope it will be below 2 kilograms and 
could go as parcel; if so - shipping price will not exceed 20 USD). I'd 
like to ask for a single "Lion".
Any questions are greatly appreciated.
I'll be back on Tuesday to this mail address. You can send your questions 
to ly2mw@ot.lt

Thanks and have a nice comming weekend!

Does the burn in procedure differ for 3-500ZG tubes? I have some new spares
