LUKASCHEK PP1 (PP-1) T-9 Phono Preamp Internals

[Celestial]

Hi,

Could someone please post close-up (macro) internal photos of the Lukaschek PP-1 T9 (SMD version) printed circuit board? (Showing the MELF resistors, capacitors etc. full 360 degree shots if possible please.)

Also, what are the part numbers of the two input transistor's on the input stage?

A friend has asked me to 'try' to repair a partially complete PP1 T9 that he bought at a car boot sale a year back.
It looks like someone had grand plans to mod the circuit, stripped a lot of parts off the board and then gave-up.

He's already been back through the Benz Micro dealer and told the product is obsolete and not factory repairable - apparently the PP1 was discontinued some years back due to unavailability of the input transistors and the Siemens polystyrene capacitors used etc. so he was told...

Thank you for your help in advance.

Ouch. That's too bad. I can't be any help but that was a lovely sounding unit at it's price point. It punched well above it's weight class.

Yes - apparently so. He 's been told that the LUKASCHEK PP1 was one of the few phono preamps that make the Glider SL cartridge sound superb. (He's got a near new Glider SL he wants to use it with.

Regards,

Hi,
Just wondering if anyone out there has ever repaired a Benz Micro Lukaschek PP-1 T9 (SMD) flavour preamplifier?

I'm having some issues (questions) about the voltages around the transistors in the input amplifier and RIAA stages?
Please share any typical voltage measurements you might have?

Thanks in advance.
