Nastavak izvestaja je zanimljiv,opisuje planove proizvodnje ,osim civilnih evropskih tipova cevi na pocetku spiska
slede americke cevi,tj tipovi koji su se trebali proizvoditi za americke radio uredjaje koje je YU pocela dobijati ranih
pedesetih,9002 masovno u avionskim radijima recimo,baterijske cijeci za an/grc9 itd.
Ti planovi za americke tipove se nisu ostvarili,osim za malu pilot seriju,ja naime imam cijev RR zavodi 6Q7 GT
sa bijelom petokrakom i znakom RR zavodi Nis.
A. Present Production and Plans
At present 300 to 400 rectifier tubes of the AZ1I type (a
European full-wave rectifier with a side contact base) are being pro-
duced daily. Pilot production is also under way for the 6K7G (an
American pre-war pentode), the EZ12 and FZ21 (European rectifiers) and
the EBL21 (an European double diode -- -- output pentode). Present plans
are that the following types will be introduced into greater production
later this year: 6K7G (Sept.), EZ12 (Sept.), KZ21 (Sept.), EBL21 (Oct,)
and ECH21 (Nov.).
It is estimated that the following quantities of receiving
tubes will be produced for civilian consumption on an annual basis by
1954:
EBL21 -- 100,000; ECH21 -- 200,000; rectifiers (AZ1, AZ11, EZ12
and EZ21) -- l50,000; and all other types -- 50,000.
On August 19, 1952, at a meeting in the Yugoslavian Foreign
Office in Belgrade, the requirements for receiving tube production to
meet, military needs for one year were stated as follows:
Battery Operated Filament Types
Quantity
lA3 20,000
lL4 140,000
1T4 120,000
lR5 80,000
1S5 80,000
3A4 100,000
3Q4 20,000
Indirectly Heated Cathode Types
Quantity
9002 70,000
9003 10O,OOO
6BA6 20,000
6BE6 6,000
6AL5 10,000
6AK5 10,000
12AU7 5,000
6C4 16,000
It was estimated by the staff of R. R. Savodi that a total of
20,000 to 30,000 tubes of the first five types would be required on an
annual. basis for civilian use. It is also estimated that the above
annual requirement for military support will increase after the first
year to approximately twice this quantity within two or three years,
bringing the total annual requirement for miniature tubes to about
1,500,000 per year.
At a meeting on August 26, 1952, it was decided to consider
the initial requirements for miniature tubes to be in the order of
1,000,000 units and to plan accordingly. Further detail on the plans
for this phase of production are given in the section, "The Future
Production Program",
