What is SC1162? If it is a transistor then I can’t find it 2SC1162 is available, are both the same?

Can you add link to PCB layout in PDF? I’ve got some problems with scaling.

Comment on Digital DC Voltmeter based ICL7107 Chip by K

Without using 555ic we can use this take pin of 38connect 2 capacitor and 2 diode as shown in 55ic o/p pin 3. You wil get negative voltage at negative terminal of the capacitor connect that one to 7107ic pin no 26 negative voltage pin. The meter works fentastic and to avoid fluctuation use tl 431 Short pin no 1&3 of TL 431 and connect to R4, through series one resistor of 1k connect to +5volt supply centre terminal of TL 431 shoul connect to Ground

Sorry, this circuit will pump out 5-7 watts MAX.! If it was parralell S.E.or a P.P. amp with 2 EL 34’s it could ,maybe… .Physics are just that .You cannot get a quart of juice with only one lemon…

Comment on 20W Power Tube Amplifier with EL34 by phillip jones

20w? An EL34 operating in single ended mode is only capable of 12w. And as people have said the bias supply is the wrong way around. Also the EL34 operates best at 250v anode supply with 100ma of anode current with a 2k anode load. They sound really nice single ended with those parameters.
Hope this helps
