Switchable Hi-Z input impedance, how ?

[tinitus]

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

 

[tinitus]

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

need to decide on trafo voltage

 

[tinitus]

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]

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

 

[tinitus]

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

[tinitus]

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

possible preamp 'configuration'

 

[tinitus]

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?

clean
and natural, whatever that means

the only distortion I will accept is what makes it sound in the direction of acoustic bass

actually, right now, the only pre I have between my passive bass and power amp is a simple Bass EQ pedal switch thing
works ok
it even works in bypass mode

but it tells me that my future preamp build may be all I will ever need
that feels good, somehow
but if this speaker goes active, I will still have some means of controlling the sound

I guess we dropped the distortion requirement along the way and I missed that. Should be relatively straight forward then.

Should be relatively straight forward then.

I hope so

well, may not be that simple, it seems
part of my problem right now is distortion

its fine at low SPL
but I loose the clean sound when I play just moderately louder than low

Compression.

Compression.

on its way

 

[tinitus]

Compression.

wow, it works
hard to imagine playing without it now
like night and day, really

 

[tinitus]

funny, I just now found that the compressor has a high/low gain switch, for active/passive pickups

wonder what gain will be optimal for my tube pre

 

[tinitus]

wonder what gain will be optimal for my tube pre

ordered a few 6n6p
and then decided, why not use 6n1p in front of it
so, a few of them ordered as well

got the plywood itch
had some 6mm plywood leftovers
and glued them together, into 12mm pieces
and hopefully the end result will be a nice box
