Yeah, dumpster rental and trash disposal is expen$ive these days!
Well, sorry, I'm just now on my lunch break, or I'd have seen that connection sooner.
Now, what I want to know, when is someone local going to decide to toss their old Hallicrafters gear out on the curb as worthless? I'd love to get my hands back on an HT 37, SX 111 & HT 41, with a side order of a TO Keyer to boot. I never get THAT lucky!
Sure. I needed money for a second home in 1999. Sold off several AT1s, VF1s, AC1s and a few CR1s.
Kept the best CR1 and a nice Miller 595.
A large amount of gain at the RF stage is not necessarily a good thing. Actually, the ideal amount of gain at that point should be just enough to overcome the mixer noise.
The ARRL gets calls from survivors requesting assistance. There can be a big psychological burden associated with tossing stuff into dumpsters.
My wife gave away her valuables before passed--one of the very few silver linings of dying from ALS. You have enough time to put your affairs in order.
I think it's the Swedes that call that process " Dostadning "
Sorry to hear of your loss.
My family had to dispose of decades worth of Mom's 'stuff' when she passed, it wasn't easy.
Bottom line: 6BZ6 falls off a little at 28mHz in the few transceivers I owned. The 6BZ6 & 12BA6 RF tube in the National NCX-5 does not.
The NCX-5 has two 12BE6 pentagrid mixers after the two RF stages. Pentagrid mixers are noisy as heck. The result is four stages with significant gain ahead of the crystal filter - which isn't an optimum design for best "dynamic range".

The 12BE6 has a crazy high noise figure. Using two of them compounds the problem. Also, high gain at the front end is an invitation to cross modulation issues.
If people are selling their Heathkits, that means other people are buying them, so whats the problem?
