Thanks for that info, I'll order some and run them
as a 500V cap with some safety margin.

Re: Tokyo Hy Power HL-45B question.
Assuming that the amp is functional, are you sure you that you don’t have it in standby or that it is being keyed properly by the radio.? You don’t need ALC when then amp is driven with almost any solid-state transceiver. ? 73, ? Steve ?

Fault lies in the rf hot line.? When the operate relay is switched to operate the rf line goes open circuit
|
Oh woe is me.
I have been using the linear with my Tentec Orion quite happily, manually switching the relay not via the rig nor leaving it permanently shorted as when I found it. ?I have been running a max of 500 watts into good SWR. ?My procedure has been to run the rig through the un-energised linear (mains ON, OPERATE not on) and tune for perfect SWR as measured by the rig, the SWR bridge AND the meter on the ATU. ?Then tune up the linear as per manual. ?Then operate on air.
All has been good till this morning when I find that running the rig through the linear is fine but as soon as I energise the relay the init SWR goes very high, the rig rolls back and nothing is going anywhere. ? I'm guessing its that relay gone wrong maybe?
Anyone met this before? ? Ive got the covers off and apart from some heat and life wear on various resistors (the ones between the anodes particularly ) there's. nothing obviously amiss.

Re: fl2100z / Tentec Orion 2
Yes. That is a great solution. I have a 5kVA unit with 10V taps
from -40V to +20V compared to the incoming mains. I use it on my
AL-1500 and HF-2500 amps.
I run them on 230V and they are very happy there.

The biggest single issue in this country (Australia)
with the 2100 amps and a lot of others, for that matter,
is the filament voltage. Due to our 240V to 250V mains,
it is always high.
With the 2100 series amps, the filament voltage, at the
tube sockets is typically 6.8 to 6.9 Volts.
Luckily, there is enough room under the chassis to
install some series/parallel wirewound resistors, in the
filament line, to bring the voltage back to the nominal
6.3V.
I have done this to at least 20 Yaesu amps over the
years and in every single case, it has tamed them right
down to become a good little amplifier with very few
problems.
You can do all the other mods that you see floating
around the net but I've never bothered. After the
filament voltage has been corrected, I've never had an
amp come back to me with problems.
