Can I add a buffer an inverted opamp ?
Or somehow boost the output current (discretely?).
.....and have the output as non-inverted ?

Why you ask?
I have these old "potted cube" inverting op amps that I want to use somehow.
No datasheet/ specs at all on these (Intech A-233).
I managed to build a test rig, and get this inverting opamp to work nicely at about a gain of 3-5.

Any ideas, or similar circuits that I can get ideas from?

Test rig:

Might not be an opamp:

Ha !!
I don't think so, though. I'm not that knowledgeable about VC's but that does not look like a voltage converter

???
Voltage follower maybe.

My results with test rig(w/sine input):

I was about to post something here, and saw what you found (thanks btw

)...
For the moment, until someone thinks that the diagram on the amp is really a VC, I'll assume that link seller mis-labeled the description.
...was about to post:

What if another higher current handling inverted opamp follows this one (in series).....it's output will become "non-inverted", correct?
LH0032 (100mA) ???
CLC200 (100mA) ???
Then could a volume pot go in between them?
(just brainstorming here)

Correct. For the volume, you could put a variable resistor in place of the feedback resistor.
