Tubes?

[turbo]

Jason, an all

google "hartley oscillator"...very clean ..easy to

Lindsay

at first there was the Armstrong oscillator.
Then came the Hartley oscillator and this design was improved to a Colpitts oscillator.
all of the above show resonance issues just above and below the tuned frequency.
Then came along the Pierce Miller oscillator and this was said to not have those harmonic properties.
These were the most stable oscillators.

the circuits are quite simple.
if you need any i can do a hand writing.

for all of you people here that think all i do is talk

a few coils im my pictures and just some of my gear there are more coils i have build but for the most part this is all of them to date

so turbo top it  big guy

i have spent much time on this and plan on spending a LOT more time with the tpu!!!


isteam!!

dear god!

Judging by the odds of the picture, I believe you got something or many useful items in there.

yes i have some time spent winding coils 

do not ever think i wont get it to work cuz i will!!!!

is

well all it is now time!!!!! i am setting up my table and gearing up to play with my single tube yes the 6bq7a tube the 1 steven says he uses for input and phase invertor so with some luck i will not hurt myself and maybe it might just work out for me

THE TIME IS NOW

@IS,

WOW man. Maybe you should start a TPU loan service with all those spare coils you have laying around! I'm only up to my 8th iteration .

@Marco,

The hand drawing would be extremely helpful as I am getting frustrated looking around the net for suitable circuits. How do you figure out what cap and resistor values to use for the individual tubes you have? Is there a nifty utility program out there anywhere that can help determine what values to use? (I'm guessing not )

God Bless,
