These two sites are not accessible from Vietnam, is it also the case from other countries?

The second site is the Americanradiohistory.com, before I could. Vietnamese government cuts the access of numerous websites mostly information as BBC or RFI, as ponography.

Instead of starting my work week, I found myself browsing those fascinating old gems. Came on this Leak advertisement for an amplifier. At that time, we called frequency cycles/sec instead of Hertz and a remote control had a tick cable. At least you didn't have to change the batteries 🙂

30 pounds of magnet, and an 18 inch cone,
Seem to be an entertaining article.
Sometime, in 1960 ....

This article, actually changed the course of audio design
Picking Capacitors - Walter G. Jung and Richard Marsh

Another article that changed the audio landscape,
Was the JBL subwoofer piece, in August '83.

i am looking for the 1980's article about the 40 year history of solid state amplifiers on the Audio Magazine...
Re the "Picking Capacitors" series, I was always amused at the picture of butler-type person proferring the caps on the tray - from the impudent expression on his face I thought he might prefer to be sticking those caps on the tray up your nostrils or maybe some other orfice...
I have wondered about 300b. Typically 8w or so SE, Allen Wright claim his PP 300b does 25w Class A, so AB more?

I'm pretty sure that's Richard Marsh himself. Rare to get your picture on the cover of a technical magazine. Can anyone guess who's the only person ever pictured on an Audio Amateur cover? (Hint: Paul )
All good fortune,

Here is the "Audio" index from 1965 to 1999.
"Find" in this pdf word "Bongiorno", or any other keyword...
There are several articles from this author, but nothing of that nature...
40 years history of transistors amplifiers even in 1989 will start that history in 1949!
What kind of transistors amplifiers were in existence between 1949 and 1968?
Read the beginning of the posted article from 1988...
Could it be in some other publication?

I know Bongiorno wrote a construction article on his 'Ampzilla' design in then The Audio Amateur.
He ran into problems because by the time it was published, his output devices were obsolete.
The design (or similar) has later been commecialised by his company GAS (Great American Sound).
Must have been late 70-ies I think.
Edit: fig 2 here https://www.updatemydynaco.com/HistoricDocuments/AmpzillaAudioReview.pdf looks exactly like the pic in the TAA article.
Edit2: the design was published first in Popular Electronics, Sept 1974, as "Get 400 Watts of clean stereo power with Ampzilla' by GB.
Then Walt Jung build the kit and found some serious issues with the (unmatched) input devices, leading to an exchange with JB. This was in The Audio Amateur issue 2, 1974.
At that time, GAS announced they would hencefort only sell complete assembled amps for $809 dealer price. The manual was available for $ 2 .....

Ampzilla. We had a couple thru. One of the better big amps that were just appearing, we sampled many. Bryston 4B was better and better made (but not as pretty). The 50 & 70 watt NAIMs sounded better but cost more. Hook the amps to XG8s and the NAIM out powered them all. The other that stood out was the Dreadnaut-Clark but they were not around for long. Never got the chance to hear the Marantz 500. Most of the early big output amps were not good, some downright terrible. DC300 a good example of that (& the BGWs)
