Just had a look on ePay.com at completed listings, Ballantine VTVMs don't seem to sell very well, lucky to get $20 to $50 for one, the manual costs as much as they are worth.
The 321 is supposed to be similar but with extra functions (according to the catalog) but no free manual either.
Not sure it's worth repairing & flogging, you would probably need to change all the paper caps, would be rather time consuming for not much return.
One for the US members, is the Ballantine 323 TRMS voltmeter better or worse, than the HP 3400A?

The type 320 manual is no use for my 320A

Yes, not worth doing and restoration on this thing before selling it. Either I sell it as is, which was my intent all along, or I restore it to keep it for myseld.
Problem is, restoring this thing would be costly, time consuming and a pain, given how it's built, if not unrealistic / impossible, given the absence of manual / schematics for it.
Trouble is, I don't have a need ot enough love for this thing to embark in a restoration, I am choosing my restoration battles now, and thi sTE does not fit in the picture.
I feel guilty.. because it's technically a really cool piece.. a true RMS meter made from hollow-state tech, I must say I am quite stunned.
But I have no use for this thing and no room to keep boat anchors I will never restore / use.
OTHO I can get myself to tak eit apart for parts.... it's worth much more than the sum of its parts. It deserves to live for sure....
so I need to find it a good home that will restore it..... yes I know I am dreaming.
So I will stick my plan.... sell it as is. I did the basic safety checks, powered it up, there is life in it, so it can probably be fixed.... so I can sell it as such.
It's in good nick inside out, it's not a rust bucket at all. Just a bit dusty inside so needs a little wash. Outside I can give it a clean to make it more presentable, but that's as far as it will go.
I will advertise it at 50 Euros to begin with, and offer shipping. I mean... not going to pay for shipping, just offering the option to ship....
I really want a good home for it, so I am wiling to pay for card board boxes and packing material and go through the hassle of packing it.... if it can help it find a new loving home.
If I advertise it for less than 50 Euros, it might start attracting the tube hoarders so I might as well take the instrument apart myself....
So that's the plan... I will clean the front panel, put it up for sale for 50 Euros, and if I have no takers in 3 months.... I will reluctantly scrap it for parts... and feel guilty for the rest of my life
