G'day DIY-ers

Hi Everyone!

I'm a long-time DJ and more recent Mechanical Engineering student. The latter is a bit of grind in my late-thirties, but bit-by-bit, we're getting through it.

Making some speakers is on the cards and something I think about way too much. I'm hoping with all the signals-processing maths they're cramming down my throat, I'll be able to build something nice one of these years.

I'm reasonably handy with a soldering iron, one of my jobs is assembling through-hole PCBs. I don't know much about electronics though. About I'll I know is "Inductors will bite me" and what capacitor does.

My home set-up is pretty humble.
For the Amp, I've got a Technics component amp (SU-Z11, SH-8015 EQ).
The speakers are some nice, home-make units (not of my doing) with RS-150-4 and Vifa BC25SC55-04. They measure 3.5Ohm across the terminals, which I'm guessing translates to 4Ohm inpedence, not that I know what impedence is.
For the Turnie, SL-1200 with a ortofon OM cart and Nightclub MkII stylus.

I love the asthetics of the technics amp, but is probably the weakpoint in my set-up. I recently found a Sanyo DCA-200, which I was hoping would give me a bit better fidelity. My dumb *** purchased untested and sure enough, the Left channel is putting out nothing but hum. I've found a thread suggesting what transistors to use in replacement, assuming it's the source Mosfets causing the issue.

I also have a old Yamaha monitor I'd like to refoam. Got the replacement foam, just need to have a crack at it.

Anyway. Thanks for having me. Look forward to chatting soon.

Barry.
