Hi, Thanks for your layouts. I've got problem with the erupter. True Bypass,connections and components seems to be ok. No bad link between strips. LED is ok but no sound. Did you solder or put in contact TL019 housing tabs with link (ground), the other, the two, no ?
I used a pf5102 and two pn2222's. I get oscillation if I turn the bias pot lower than roughly 85% clockwise, regardless of the 5k trim pots position. could this be because of too much gain? when I have the bias pot fully clockwise it sounds pretty damn good but I don't want to settle for a single setting if i should be getting more. Please help. Thank you in advance.
Hey I'm not too familiar with using the transformers in circuits(semi noob here) I have a 42tl003 audio transformer. would that work with this circuit? or is the 43tl019 specific ? also this site is great, thanks for all the effort everyone.

Hi, there.
DeleteNo, I snipped of the tabs of the transformer since they don't need to be connected.
Have yoyu checked the pinout of your transistors? And checked your voltages?
I use 2n2222. It's reversed compare to your layout.
ReplyDeleteIt's ok now, thanks !
