Larry, I've enjoyed looking at your radios and thank you for sharing them with us.
I do have a question- if this was made during the Red China era, and never meant to be exported to the west, why are some of the dial markings written in English?

Nice radio! From looking at the pictures you posted earlier and on your site, it looks like they were building tube radios in China into the late 1970s/early 1980s - almost 15 years after they stopped in the US. Very interesting

Sure, never meant to be exported to the west, because during the Red China era, There's no west country made a diplomatic relations with Red China. During the Red China era, The Chinese government to turn the radio as a country gift given to foreign guests. (to Africa, Latin America country) Look these pictures, maybe you can understand:

I guess that would explain why the print (schematic diagram) was written not in Chinese, but in English as well.

While there was little diplomacy between China and the West back then, it looks like China used some tube designs from American and European manufacturers, no doubt supplied by the Soviet Union. During World War 2 and the Cold War, the Soviets often took designs for parts from American and European manufacturers. The Soviets usually made direct copies of the original designs, but sometimes they changed the characteristics or rearranged the pin connections. Two of the tubes in this radio are electronically identical to two American tubes: Data sheet for type 6A2: http://scottbecker.net/tube/sheets/095/6/6A2.pdfData sheet for its American equivalent, type 6BE6: http://scottbecker.net/tube/sheets/127/6/6BE6.pdfData sheet for its European equivalent, EK90: (German) http://scottbecker.net/tube/sheets/062/e/EK90.pdfData sheet for Soviet equivalent, http://scottbecker.net/tube/sheets/112/6/6A2P.pdfData sheet for type 6K4: http://scottbecker.net/tube/sheets/095/6/6K4.pdfData sheet for its American equivalent, type 6BA6: http://scottbecker.net/tube/sheets/127/6/6BA6.pdfData sheet for its European equivalent, type EF93: (French) http://scottbecker.net/tube/sheets/020/6/6BA6.pdf; (German) http://scottbecker.net/tube/sheets/062/e/EF93.pdfData sheet for its Soviet equivalent, type 6K4P: http://scottbecker.net/tube/sheets/112/6/6K4P.pdfThe other tubes are not as easily translated. The 6N2 seems to have electronic characteristics similar to those of type 12AX7/ECC83, but with different pin connections. It has the same pin connections as a 6AQ8/ECC85, which seems to be the closest Western tube to the original. 6N2 data sheet: http://scottbecker.net/tube/sheets/095/6/6N2.pdf12AX7 data sheet: http://scottbecker.net/tube/sheets/127/1/12AX7.pdf6AQ8/ECC85 data sheet: http://scottbecker.net/tube/sheets/010/e/ECC85.pdfThe 6E2 tuning indicator seems to be equivalent to European type EM84, but with the target connection moved from pin 6 to pin 2. If you connected those to pins on the socket, you could probably use an EM84 in that radio. EM84 data sheet: http://scottbecker.net/tube/sheets/010/e/EM84.pdfThe other two tubes have no direct replacements with American tubes. Both of them have pin connections that were not used by American manufacturers. However, the 6Z4 looks like and has similar characteristics to American 6X4. (There was an American tube type 6Z4 which was used before World War 2, but it is a larger tube than the 6X4.) Chinese 6Z4 data sheet: http://scottbecker.net/tube/sheets/095/6/6Z4.pdf6X4 data sheet: http://scottbecker.net/tube/sheets/127/6/6X4.pdfThere does not seem to be any American tubes that are similar to type 6P1.

That still stikes me as odd. There is a lot of Africa and Latin America that does not speak English. So why not Spanish or French? It just kind of surprised me. Curtis Eickerman

"""""There is a lot of Africa and Latin America that does not speak English. So why not Spanish or French?""""
English is the international language If one has resources for only one foreign language then English is it I have worked for two companies that market scientific instruments around the world and have been in training class with other field service engineers that had to be fluent in English.
The language of S A P, which is a German company, is English
Of course the French are mad that French is no longer the international language
One time I was installing an instrument made in Australia and lo and behold included was a small screwdriver made in the People's Republic of China and this was before Nixon's visit. It was illegal to import this screwdriver so I took it and replaced with a screwdriver from a hardware store. The issue was not going to blow up on my watch!

Larry. Very nice collection. Thanks for sharing it with us.  I look forward to seeing more in the future. I note the radio has a "German" sort of design to it. Reminds me very much of Grundig, Telefunken, or Lowe sets. Especially the IF cans. I suspect this may have been a very well built set, as I note one tube uses what appears to be a ceramic socket on it.

I noticed the adjustment holes in the back side of the cans as well. I think it's more of a general European design, rather than limited to just Germany. Here's a Chech "Talisman" with the same IF can design;

Here's a Chech "Talisman" with the same IF can design;  In the United State called Philco, In Red China called FeiLe or FeiLei This is FeiLe Model 261A tube radio that I fixed it. 6 tubes. very like Grundig 97B right?

The FeiLei you have does look very similar to a mid-1950s Grundig or other German set. When was it made? What is the tube lineup?
