I am new to this sight.
I have built several 6T9 amplifiers using the Spare Time Gizmos PCB with great success.
I built one the other day and when I fired it up it was garbled mess that came out.
I looked it over and noticed that i had put 270,000 ohm 1 watt resisters instead of 270 ohm resisters in Rs 105 and 205.
When I put the correct resisters in the amp stated playing but when turned up it would start to chirp nasty little barklike chirps.
Would anyone have any idea what might cause that.
Thanks for your time,
