so here is a schematic http://www.freeinfosociety.com/electronics/schemview.php?id=799 (sorry i don't know how to get it to show up better on here).

i chose this circuit because it is very simple. i am planning to build 5F1 based on these schematics, but i would like to only do the preamp.

i would like to build a power amp as well, based on the same power amp. but use the power amp for another preamp (another champ variant)

i am trying to figure out if i could use a different kit amp with it, still 5 watts.

is this reasonable? waste of time? stupid? let me know.

thanks in advance.

not really worth it for a 5f1 circuit.

it barely qualifies as a preamp and a power-amp.

cut it wherever you want.

make sure you get a transformer that accounts for the difference.

I wouldn't try to really separate the whole shenanigans into two units, rather, I would put a preamp out jack and a power amp in jack. That way you can pipe out of the pre-amp or into the power amp. As for where to cut it, between the coupling cap coming off the anode of the second half of the 12AX7 and the 220k resistor to ground is where I'd cut it. I'd also add another coupling cap for the input to the power amp in case whatever pre-amp you run to it doesn't have one.

AM i figured it would be a good example here, however i maybe went too simple.

thanks.

i was going to practice on something little and cheap, than build a split plexi with a poweramp that i could potentially a different amp as well.

i am open to any ideas. still learning.
