The tube-stuff can probably be traced at a glance. The transistors won't be very fancy, but may use strange or crude circuits.

Paso Sound, 4750F Goer Drive, Charleston, South Carolina.  << traces to a Marriott hotel, which does have several other businesses inside.

"Founded:    1973  Our brief history takes us back to 1931, the year John Geloso founded our Company."

So a hunt for late 1960s early 1970s Geloso may add clues.

Their website is not working for me at this moment. Archive.org has a 2012 snapshot, but maybe incomplete.

Paso Sound Products, Inc.
4750 F Goer Drive
Charleston, SC 29406
TEL: 843 308 9005
FAX: 843 308 0904
TF: 1 800 231 3034

There is an email contact page. I hate those; also may not work through Archive.org link. I looked in the source code for a mailto -- no, except there is this funny-stuff:
var _rwObsfuscatedHref0 = "mai";
var _rwObsfuscatedHref1 = "lto";
var _rwObsfuscatedHref2 = ":in";
var _rwObsfuscatedHref3 = "fo@";
var _rwObsfuscatedHref4 = "pas";
var _rwObsfuscatedHref5 = "oso";
var _rwObsfuscatedHref6 = "und";
var _rwObsfuscatedHref7 = ".co";
var _rwObsfuscatedHref8 = "m";


Pasting the small variables together I get:   mailto:info@pasosound.com

However if their web-site registration has expired, their email is probably abandoned also.

I did not know who Geloso was. Interesting.

Paso Sound; Charleston (SC)    (USA) 
Abbreviation:    paso
Products:    Others
Summary:    

Paso Sound, 4750F Goer Drive, Charleston, South Carolina. Paso Sound wurde 1973 von Geloso electronics abgesplittet, und als separate Firma aufgebaut.
Founded:    1973
History:    
Our brief history takes us back to 1931, the year John Geloso founded our Company. Geloso, a pioneer in the Electrical and Electronics fields, emerges into history as one of the "forefathers" of today's electronics' industry. In 1919, as a young immigrant, he came to America from Genoa, Italy, immediately fascinated by the potentials of electricity, especially with Marconi's Radio Transmissions across the Atlantic. Subsequently, he worked for one of the radio and telegraph shops that opened on Cortland Street in New York City. In 1924, he graduated in Electrical Engineering at the Cooper Union University: the college where Thomas Edison had also studied. Geloso then joined Pilot Electric Manufacturing (PEM) and became project engineer for what was then called "The Magic Lantern", the beginning of television. The first transmission experiment took place in 1928, between the transmitter located at Station WRNY in Coytesville, NJ and the receiver (designed and built by John Geloso) inside Philosophy Hall at the New York University. Witnessing the experiment was Lee De Forest, the inventor of the "Triode Vacuum Tube". The screen was only 2 square inches but it clearly showed the image of a woman smiling.(Geloso's wife) (Text von der Paso Homepage)
Our Company, then called GELOSO ELECTRONICS, engineered and produced over 2000 professional, commercial and consumer products from the early years of operation until 1972. Products included: Audio and Sound Products, Intercommunication and Security Systems, Radio and Television sets, Transmitters, Receivers and RF Communication Systems, Tape Recorders, Dictating Machines, Medical Equipment, Components and countless other products manufactured under various OEM Labels. Twenty-four factories were built in North, Central and South America, Europe and the Far East to satisfy distribution in 53 countries worldwide. Many innovative products covered by over 2000 patents were introduced, including, in 1954, the first compact consumer Tape Recorder, manufactured in large volume (more than 500,000 were produced). In 1956, the first Solid State Tape Dictating Machine was manufactured for Mc Graw Edison of West Orange, NJ under the Edison Voicewriter label and more than 1 million Voicewriters were produced (Text von der Paso Homepage)
In 1973 the privately owned Geloso Electronics, producing over 3000 products, was split into nine separate divisions. PASO SOUND was born inheriting the patents and "know how" with the intent to continue producing Professional and Commercial Sound and Audio Products (hence the name PASO - for Professional Audio & Sound). Today PASO SOUND is part of a multi-national, multi-billion dollar conglomerate, Butan Gas S.p.A. engaged in refining natural oil and gas products. The ELVOX Division, initially formed to produce Intercommunication and Security Products, is a one hundred million dollar leader in this industry today. Projecting into the new millennium, the continuous success of our company stems not only from a strong engineering and manufacturing background, but also by more than 70 years of experience in the Electronics and Intercommunication Fields. Thank you for choosing PASO and ELVOX Products as your applications provider. (Text von der Paso Homepage)

This seems to be a Dutch site for Paso products
http://www.redstarelectronics.nl/

The pasosound.com domain is registered til spring 2018, but I seem to be getting a DNS failure, meaning they let their DNS registration expire (or cancelled). That might be a few-day glitch (with holidays, maybe next year), but could also be the company has quit business.
