Yes, that is a problem. I did something like that a long time ago. I put the wires on the outside.
And the extra weight at the worst place...supply wires having resistance...Lots of issues...not an easy task...
Hi there,
some twentyfive years ago i was employed at
a pcb-manufacturer.
Amongst other threads we did pcb's for environment-
sensors, they measured about 40x3x1,5mm. Multilayer !
So, why don't just stuff it in the Armtube ?
Shielding for free...

i must admit i am a fan of straight trackers e.g. the conductor from cartridgeman, or the turntables from bergmann audio (if only i would win the lottery... ) these tonearms tolerate even less weight on the headshell.
what if the headshell were a PCB?
The Calderas may be a bit too honey dipped in the fundamental tones and i have heard more squiky clean and focussed but man, do this ancestors have space and SOUL.
Volume is more then enough with my 20W class A amp.
This is still a very modern concept : Linear Phase, fully modular, pneumatic baffle. The cabinets are made from " dancing floor ", a sandwich material with a soft internal layer.
The midrange cabinet has a steel double cross that is tunable.
Of cause i made some changed, substituted the Scan Speak 29mm soft dome with a modern ring radiator and the woofers have a proper rubber surround now. But still i am surprised about how much thought and innovation went into this speaker.

I am using the ADA4898. That chip can drive very low impedance so i use a 100 Ohm feedback resistor. That gives with my Titan i 100/6 = 16,66..
Are you also using a feedback capacitor?
I assume that you are using +/-5V supplies with decoupling caps caps close by, but I can't figure out the other two resistors that don't seem to be the where the feedback resistor would be.

No, when you go over 100 Ohm with the ADAk4898 you need a feedback cap or you can get speak. This is described in the data sheet.
Joachim, I try to understand every thing in this thread, but this escapes me, what is "speak" ? 🙂 is it a typo or ...
