nice.thats circuit sir is working 100%

 

[jhongodpeavey]

me to sir..

for the apex, if the scheme is whether the psu could be better used for h900 apex,

 

[AndrewT]

No, does not work.

 

[wattaniya]

h900 tef,
any mistakes let me know.

 

[wattaniya]

which resistor is better?

 

[khalsa]

E15 5W best

 

[khalsa]

E15 plate resistor for good result

 

[wattaniya]

hi apex sir,
for the h900 tef r23,r22 7.5k is it correct?
what is the emitter resistor voltage mv for h900 tef?
can u check the image for errors. because i am going to make the silk screen.

 

[wattaniya]

E15 5W best

thanks for the reply khalsa.

 

[irvynejay]

crest output

1st transistor is driver then the following are the power outputs

pls ask mile for modification

 

[wattaniya]

check this image,

 

[donpetru]

@nazirdigi, both resistors are going very well.

hi apex sir,
i already asked some questions from u in h900 thread, but u didn't reply, pls reply to this.
which schematic h900 triple darlington u suggest for PA, with the bias pot 10k or 1k pot or without pot.
and r23 7.5k, can u share the correct schematic, i know u already shared that, but i dont know which post is that.
thanks

Use 1k pot (or without pot) with MJE340 for Q5 (Vbe multiplayer bias transistor). 10k pot use with darlington for Q5 (like BD681...) i dont know which post is thats schematics.

thanks for the reply sir,
is this correct for triple darlington?
what is the emmiter resistor bias voltage?
