Hafler 9505 service manual doesn't match actual amplifier?

[300b]

Hi All,

I have a Hafler 9505 amplifier I'm trying to debug. As always, I tried finding the schematic and service manual online. Luckily, I was able to find a few files. Not so luckily, the component values don't seem to match the actual unit.

I was wondering if someone else ever repaired a Hafler 9505 and noticed these variation, and if you were able to find the actual (correct) service manual?

Looking online, it seems there are 2 variants of this amplifier. The one with the XLR on the top:
Hafler 9505 Transnova Power Amp | Adam's Gear Garage | Reverb
One with the XLR at the bottom:
Hafler 9505 Transnova power amplifier Photo #1414718 - US Audio Mart
The unit I have has the XLR at the top. I have no idea if the two units have a difference in the actual schematic, but I assume it might explain the differences.

While it is possible to try and debug without the schematic, it typically makes things move slower. Any help finding the schematic/component values of the amplifier I have would be highly appreciated.

Hi 300b:

I few years ago had restored a 9300 series TransNova (almost identical to the 9500 series but using 6 output pairs of K1058/J160 instead of 8).

Perhaps the schematic may be useful for you (please disregard my restoration notes in red marked on it).

Hi Mayank,

Thank you for posting. I was able to find this schematic online as well (used it for 9300 series I had on the bench some time ago), but unfortunately it doesn't match the 9505 I have at the moment.
