You will blow the fuse if you spend too much time with the key down.
I used to run RTTY, reducing the power to 60 watts or so. You would
be safe tuning up in TUNE position, but need to go CW for the full
power touchup. There should be no reason to lean on it for more than
5 seconds at a time.

Nutralization is easy. Adjust bias for 55 ma. no drive, then tune
up the radio normally on 28 MHz. and switch the screen grids off on
the back panel and adjust neut cap for minimum output on a receiver.
Use an insulated screwdriver or you will burn out the plate choke.
When you are through, plate dip and maximum RF output should be very
close (but not usually exactly coincidental) and maximum RF output
should occur at 225-250 ma. IP. Always tune rig for maximum RF
output for cleanest signal and reduce drive for your needs.

Fuse value depends upon what line voltage the unit is set up for.
The TS830S
can be either the 110VAC or 220VAC....you know.. higher voltage
lower
amperage.

Neutralization need is not indicative of a power supply problem..
look at
the rectifier unit assembly and check for a problem there.. ripple
, hum,
wrong primary winding wiring set up.

I bought a TS-830 from a ham friend that buys estates etc. He
couldn't
get more than 30 watts out of the '830. I tried it and by putting
the
drive control at a low level then dipping the plates and
adjusting the
load control and finally increasing the drive control I was able
to
get 100 watts out. Then the rig went dead. I checked the fuse on
the
back and it was blown. It was a 3 amp fuse but right underneath
the
fuse holder in white lettering it said 6A I'm wondering if the
'830
should have a 6 amp fuse instead of the 3 amp fuse that was in
there ?

Also I noticed that even when the plates were dipped correctly
that
the plate current meter at 100 W out was almost pinned to the
max,
maybe it needs neutralization ?

Thanks in advance.
