NB: The ECH tubes can certainly be used in AF amplifiers (just like e.g. ECF80). And in my younger days, people often used 3-4 pcs. ECH21/UCH21 when they wanted to build a cheap, capable shortwave radio. The resistance movement's "Telephone Book" from the war used UCH21 and UBL21. NB: See also my other tube ads.
