ok had fun with this amp I tried to add 2 control circuits with no luck.
again im new to this I've looked at several scrematic on tone control
i'm just not getting it.most show a in and a out.
but the way the tone is on the noisy cricket there is only a in no out
I think. the tone is in parallel with the volume. can some one give me
a crude schematic of 2 tone controlls that will work with the noisy cricket
or/and some links of info on tone control that might help me
thanks frank

I figured out what the problem was I had the input/output jacks
wired wrong hot and ground reverse. thats a little embarrasing
not sure how it even worked at all. I built it on a breadboard and
it sounds really great  surprised by the sound I'll mess around
with different tone circuits and the gain.
next project will be the "murder one" 6111 tube

Quotehow do go about
testing out a circuit before you build it into a enclosure

My personal solution is an Epiphone  blues custom 24" steel chassis. it has 3 octal 5 9 pin holes and mout points for lots of pots and switches. is large enough to mount nearly any thing including breadboards in it AND put transformers outside. It also sets in a 10 by 8 by 36 "blank" plywood head cabinet that the chassis opening is lined with speed tape (heavey metal tape) for shielding.

I can build almost ANY AMP in that

any pics of that sounds like something i would want to build.
like most people here I want to learn how these things work
wanted to start small next build a small tube amp and so on.
but I need to be able swap out componets/add things
thanks for all the replies

I think your amplifier starts to oscillate with high gain and tone on "bright".
Probably a layout , shielding or grounding problem, difficult to solve by "remote control".
Did you build it in a metallic grounded enclosure?

I think you might have found the issue.
I didnt think about shielding at all didn't even put it in a enclosure.
I got out my bread board today to change and test diferent parts.
this amp sounds good at lower tones but as soon as turn up the
tone it cuts in/out and all fuzzy. even the volume workes great til about 9
then cuts out. the gain really confuse me with a grit switch installed.
I thought I couldn't tell much different with the switch.
it turns out it sounds best with the switch on nice beakup but with
switch off it gets a little fuzzy and cuts in/out when gain is turn up
not clean sound at all. so I decided to take it apart and start over.
I was going to build the smokey tone amp on a bread board and once
I felt it sounds right start adding tone control/gain/volume one step at
a time. but it sound like shielding might be a issue. how do go about
testing out a circuit before you build it into a enclosure

thx for the info. after reading more post on this amp I seem
to have the same problem as others. the 3 pots cant be turn
up at the same time. I checked the tone pot for resistance
and it seems fine, is there a way check these pots to see if
its bad? I think the tone pot is bad because you can hear
a audio click noise at the same point when turning. will change
it out today.

I built mine just like the schematic says
anyone has ideals on what I should change caps/pots/res value
also I used a nine volt battery I might try play around with different
power supplies any ideal here? thx

my first amp build went with the noisy cricket.
the amp sounds great but when I try to turn the tone
clockwise about a 1/4 of turn the amp will cut in/out
get real fuzzy sounds not playable at all. also not
sure if related but the grit switch has very little if any affect
on the sound but the gain works fine.
I built this with the radioshack board and parts.
