The parts supplied with the kit are great and meet the requirements for functionality, quality, and affordability. But I am a circuit modder and will try almost anything that makes logical sense and not ridiculous.
I have installed the Gold Point Mini-V (dual 50k) in my ST-120 with the low-gain VTA board. I was looking for more range (less change) around the 12 o'clock position as that is my sweet spot for listening usually. I don't use a preamp so this attenuator is my sole volume control. Like Bob mentioned the Mini-V is much bigger than the supplied attenuator and will interfere with the circuit board. I had to file the slot opening slightly (down and wider) so the Mini-V would clear the circuit board and fit through the slot opening. There are high voltages in this area so full attention is needed. Doesn't take a lot of filing but the chassis is strong so be prepared to do this for a while until just right. Then, for reassurance I placed double sided tape on the VTA board below the two Gold Point Elma circuit boards. If the Mini-V moves it will rest upon the tape.
It is very tight fit but does make it OK even with the bottom cover reinstalled. Sounds great and have more range. I am going to open the amp up again soon to try some different coupling capacitors (modder addiction is powerful). I'll snap a photo at that time. Scott
**EDIT** Here's an inside picture with the Gold Point Mini-V and coupling cap change.
