Switchable Hi-Z input impedance, how ? - Page 11

tinitus · 28th March 2012, 02:24 PM

no

well, maybe the higher gain of ecc83 would be to have

my cheapskate effects are a bit noisy, and thickens the lower mids at higher level

and that is exactly what Im trying to avoid
so it seems Im still far from 'my sound'

I have ordered the new Palmer Deepressor pedal
but on backorder

hmm, 7025(ecc83) input tube with ecc88(6DJ8) output(buffer)

need to decide on trafo voltage

tinitus · 11th April 2012, 09:16 PM

ok, I got the Aikido mono solo boards
it will be my instrument input

and I expect my two channel Burning BA-3 (NelsonPass) will look like this
this will be my output gain/buffer

now I need some power supply parts

tinitus · 13th April 2012, 05:48 PM

going to order trafo

planned voltages

0-195-215-235 (100mA)
maybe 100mA is a bit high for a preamp, I dont know ?

6.6-3.3-CT-3.3-6.6 (1.5A)

0-18 / 0-18 (1.5A)

and maybe I would like exstra voltages for effects, 0-9-12-15V

maybe getting a bit complicated in one trafo

BA-3, a full ground plane seems to make sense here

and where a hot connection is needed, I will just route away with engraving bit
a hybrid combination of hard wire and hole mount

would be really nice to have a small tool to route around the holes

old thread, but might be worth reading

12AU7 vs 12BH7 vs 6CG7

tinitus · 16th April 2012, 11:08 AM

trafo ordered from Toroidy

0-195-215-235V (110-120mA)
6.6-3.3-CT-3.3-6.6 (1A/2A)
2x 18V (2A)
special audio quality

tinitus · 26th April 2012, 08:43 AM

possible preamp 'configuration'

tinitus · 29th April 2012, 07:21 AM

had a lucky day

guess I will have to build my own 'power brick' now

Do you have any bass sound you are shooting for? What have others done?
