Checking these HO-5960's out now (June, 2020) shows they're not such a bargain anymore... Price for a pair, shipped, was $56. So I got the well-proven K240's instead, with free shipping, for a few $$ less...

Any other Heathkit fans? I built a 5-band shortwave kit. Loved it!
I remember them well. I never built a shortwave, but Heathkit was great.
I used to drool over their catalog but never could afford what I wanted. So I started fixing things to teach myself, and building stuff from parts of old tvs and radios people gave me.

The only problem I ever had with Heathkit was a mismarked diode (their supplier's error). I installed it according to the marking, but it shorted the power supply and blew the fuse. Took me awhile to figure out.

Greetings from the North,
Ladies & Gentlemins... In all my years of playing I have just done one of the most dumbest things ever.
By not paying full attention I inadvertently plugged an extension cable from my Rumble 200 combo into a tube amp instead of a 115 Rumble extension cabinet. (Don't ask.) There was the obligatory sound of ZZZZZZZZZZZZZ! before I shut off the Rumble head power switch followed by the the whiff of crispy electronics but no smoke. The tube amp was off and doesn't seem to have been damaged. There is now no sound from the speaker except for a pop when I switch it on. The headphone jack works fine but I already have a headphone amp and the Rumble 200 is just a little too large for just that.
So.... Since it will prolly be a week before I can get it into a Fender tech I was wondering if any of you may have an educated guess as to what the damage may be?

Their bass rig used slightly larger drivers.
So, with the headphone part still good, it may be that the preamp stage is good but the power amp is fried?
I fear that's what it is but was hoping that it was something else before the power amp that got sacrificed.
unless it’s a fuse, it’s likely something in the power amp. But I don’t know enough about class D amps to guess.
I’m still wondering why it blew. Normally with SS amps (tho again, unsure w/ class D) a short is bad, but higher resistance is fine (the opposite of a tube amp). Maybe the tube amp’s input resistor blew and as things liquefied there was a brief short or arc to ground. The tube amp will work without that resistor.

If it's something in the ICEpower power supply module, I've seen one for the 200 online for $118. An expensive 'oops'. Hopefully, it's a single component that can be replaced.

one of my first amps was a Heathkit TA-38 that i built myself from their kit in early '68. i thought that it was great at the time until i bought a '62 blonde showman with the 15" JBL tone-ring cab in mid '69, i was hooked on fender tube amps. i still have a T-38 but it's just thead without it's combo cab.
I have added a Rumble 112 cab to my 500c. It is more power than my little band will ever need. In fact I mostly use the 112 extension cab with a Rumble 200 head I bought used !
