@ duff  THANK YOU SOOOO MUCH I HOPE YOU HAVE FOUND WHAT I HAVE ON THAT SITE

that is a really good link you posted there wow is all i can say  and i havent even looked at the tubes yet!! or all the books

but let me tell you the magnetic amps look verry kool and much like the tpu

a question about 6bq7a triode tube

the first tube acts as a high speed switch? and the phase invertor  tube acts as an oscilater ? inverting the siginal?

for all 3 freqs?

will the 6bq7a act as 3 indivual switches? if so how would i wire it up?

thanks



for all who are wondering what i have found here is the link im sure this is golder tpu basics and i now beleave the tpu is a magnetic ampiflyer thanks agin duff read the entire book here is the link

enjoy

if you will work , with tubes  e88cc  and others

thousends of page are in www.

cant understand that you asking for circuits.

also high voltages are NOT dangerous (BEACUSE only some mamps are needed for preamplifier tubes.)

Nobody will died with that !

Pese

someone with more experience must read this book from pg 207 to 230 it is how we might be using thease tubes for the tpu please have a look at it it is on the link from duff it is the book called lauer_radio_enginerring im having a hard time with it but it does make much sence on how it could be hooked up


ok you all here we go

here is a another book that should be looked at  on pg 224 it talkes of tube driven beat freqency osolators hummm

the book is called basic radio the esencitals of electron tubes and there circuits  by j barton hoag



in this book on page 345 is a secematic  for a blocking osoliator using tubes also it tells us of the regenerative part  of the circuit  the book is electronic transformers and circuits  there was also a plused hifreq transformer


ok guys here is another data sheet fot the 6bq7a tube  but notice at the top of it it says for tv tuners using  dirrect cuppleded cathode  drive circuits

also it says 6.3 volts @.4 amps for the heater and in some of the schems that is all that is needed to create a regenerative osolatior circuit  hummmm it sounds like supply the heater and let the tubes convert the power

here is the link for the data sheet http://www.classiccmp.org/rtellason/tubedata/6BQ7-A.PDF


if you are still hungry for more here is another book  on pg 68 it talks of voltage amps using triode tubes and they sound right along the lines as the tpu aswell  the book is called  electron tube circuits well worth the read



ok some where i was reading today it said about beat freqs and it was talking about the diffrence between the 2 freqs eg..   freq 1 is 5kh and freq 2 is 6 kh  the collector coil should be tuned 1 kh or the diffrence between the 2 freqs should be close to 7.8 hz in the tpu case does that make sence  ?

a freq gap between the beats at around 7.8 hz

just 1 more question for tonight will 1 6bq7a do it all for 1 freq? i mean will 1 tube send a signal then recieve that same signal back agin then phase invert that signal send it off then get it back agin then amp it to output? all just with the 1 tube per freq? can a triode do that?

Also  in the `50  come an lot of tubes in germany also usa  (rca and telefunken) that worked
at 6 volt and 12 volt ANODE SUPPLY !!

There are two experimenting kits (Franzis Lernpaket R?hrentechnik and Lernpaket R?hrenradios) that include such tubes (the kit creator has even written a book in German about tubes working with 6V-60V). However, they might be slower at these voltages (the speed of the electrons passing from cathode to anode is proportional to the square root of the voltage, so it depends what the distance between cathode and anode of a particular tube is to compare the different voltages).

On a somewhat related note, tubes seem to be more popular again since I've just seen there are even some R?hren-Workshops about them in Germany.

here is 1 more thought if tubes run slower on 6 -60 volts then how about the ramp up time and time  where the tpu adjust its self to self reaosnance is that the tubes warming up or building up voltage for it to properly work after ramp up the tubes have power fore use externally

well it kinda fits things
