Power Acoustik TS1920-2

[Metal100]

I need some pictures for a Power Acoustik TS 1920-2 circuit board and plasma daughter board. The plasma board wiring was removed and I need to know how to relocate the wiring. If anyone has any pictures please share them. Thank You

I don't have photos of the 1920 but on the 1440, it appears that the red goes to the center leg of the large transistor near the 494. The black leg goes to ground. The brown lead goes to the two diodes connected to the two 470k ohm resistors in the audio section.

The red lead will have very high voltage on it that may not discharge when the amp is switched off.

I think this amp comes by the name of "SPL" in Europe
I hope the pics help.

The same boards are also used by Kole. The plasma sphere version has a small, high voltage power supply to drive the plasma discharge tube.

Here, the "plasma" feature comes with another model

Thank you, Mr Babin, for the pictures and information. This should help me get this amplifier going again.
