htx-100 problem

[kk4fpx]

I was making qso's with a Texas club for 10-10 numbers when my htx-100 started blowing fuses.:( after 2 fuses I switched to my htx-10 and finished my qso.Any ideas why my htx-100 started blowing fuses?

I think I found the problem.I was useing 3 amp fuses,the manuel calls for 6 amp slow blow fuses.

I think you will enjoy the slow blows much more.

So will Manuel, that's what he was calling for all along.

Damn queer electrons anyway! ;)

Anyway, back on topic, I'm surprised a radio uses a slow blow fuse.

But I'm used to Ten Tec fast acting magnetic breakers. I guess.

yall are too funny!

Hell, I'd have just put a penny in the fuse holder.

Ten-tec's early PA assemblies lacked any current limiting circuitry and would go into thermal runaway in certain scenarios. The Omni V and later rigs used a current sense circuit to limit peak final amperage - but those Airpax breakers are the only way to go with Corsair and older models. Many automotive stores carry 12v medium and slow-blow, auto-reset breakers which would be ideal for this application.

Yes, I'm aware of the Ten Tec PA oddities. Under 50 ohms in particular.

But I'm still surprised at the use of a slow blow fuse for the HTX-100.
