technics SP-25 armboard

Hi Stanwal:
The official Technics armboard is the black pre-drilled EPA-B500.
I have one installed in a SL-1015 with the EPA-A501H straight titanium tonearm and stem. It is a great arm but seems to be designed for light weight cartridges only as my Rondo Blue is too heavy. I currently have a Denon DL-160 mounted on it and it sounds great.
Rather than try to adapt the official Technics armboard for the SP-25, it may be easier to custom build an armboard out of maple or oak and use the EPA-B500 as a template for the outer dimensions and mounting holes only and position the stem hole to accept the Audioquest PT-5 arm.

They had either 2 or 3 aditional arm wands designed for heavier cartridges but they would be hard to find, although I did see one a couple of years ago. I had an EPA 500 in the 80s and it is a great arm. You could add mass to your counter weight if you wanted to use heavier cartridges but the wand/cartridge interaction would not be ideal.

Dear Priso, My plinth is SH 10 B4 for SP 20 and SP 10 mk II. One should always check. You are right SP 25 was wrong. The hole in the arm board was 4 cm diameter and I was able to adapt this armbase for the Lustre tonearm. I own 4 other tonearms but for each of those I would need a new armboard. I am pretty sure that this armboard was meant
for the EPA 500 .

Dear Sharpe, As far as I know you can get 2 extra armwands
for your EPA 500 and then use whatever cart you like. The
'S' kind extra will also do. But Stanwal should know better I assume.

Regards,

Technics used the motor unit model number in identifying their dedicated plinths. From what I found on Vinyl Engine, there are four plinths for the SP-10 Mk2 --SH-10B, SH-10B3, SH-10B5, and SH-10B7. They differ in year of manufacturer, construction and mass.

The SP-15 motor unit had two plinth options -- SH-15B2 and SH-15B3.

Way back in 2006 I bought blank SP-15/25 armboards from Russell Collins:

It's worth an email to see if he's still around and can source them.
