G’day
A friend and I are trying to repair a TT Argonaut V 516 PA board. The fault
seems now to lie with a small capacitor which is in parallel with R58 (470
ohms) on the PA board.
This capacitor has gone open circuit but is not shown on the Ten Tec 516 PA
board schematic!!! To make matters worse, on this particular capacitor, the
value is indistinguishable, owing to fading.
The resistor and capacitor is part of the 3 times negative voltage generator,
which generates -150V to ensure the PA low pass filters, apart from the one
being used, are switched out of circuit.
Please can anyone let me know what the value of this mysterious component is?
Thank you!!

G’day from Glen Forrest, Western Australia
In the process of trying to repair an TT Argonaut V 516, which has a power
amplifier/power amplifier low pass filter fault.
My problem is the schematics of the downloadable Ten Tec Argonaut V manual
available on the Ten Tec website are just about unreadable to me as a 65
year-old. 😉
Please does anyone have a PDF – or know where I can get a PDF – of the
manual/schematics which are complete/more readable than the TT download?
Even better, if they can email it to me at stevevk6vz@tpg.com.au, it would be
much appreciated.
Thank you!!!
