technics SP-25 armboard

I need to a adapt an Audioquest PT-5 tonearm to a Technics SP-25 turntable base. The round hole is pre-cut to 5 1/2" in diameter and 3/4" deep on the table base. I could buy the official, original armboard but it is designed especially for the EPA-500 tonearm assembly and would need to be adapted for the Audioquest arm. It might be cheaper to build one from scratch with all the correct measurements. Any suggestion will be appreciated.

Sharpe, I was confronted with the same problem. My plinth
is for both: the SP 10 and the SP-25. The armbase is drilled for the EPA 500. To build one 'from scratch' will not be easy. Those are thick (3cm?) and complex armboards to make.Ie expensive. My solutions was to buy the Lustre GST 1 tonearm and adjust the armboard accordingly. The Lustre has SME like base and you will need to do some woodwork to get the arm in the right position. Be very careful with spindel- pivot distance. The advantage is that you don't need some other or new armboard. BTW you can sell your Audioquest arm and buy the Lustre more easilly.

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.
