Just wondering what others are building or restoring out there, came across a poor rusted Dynaco ST-70 recently checked into new chassis and having chassis chromed too much to add to the restoration cost, went with a British theme chassis and new tube4hifi 12AU7 preamp board. Came with a good quad of original Mullard tubes picked up 3 RCA clear top 12AU7's. Will upgrade power supply and inputs and speaker terminals. What are you working on amplifier, speakers, turntables?

On the tt side I'm playing with different materials assembled together for tt mats. It's what I've been reduced to... :cry:

As soon as I have time lots of different turntables. I have a KEF kit with the 104 ab. I'm going to get working on some interconnects and speaker cables. :D

Last week I ordered all materials to build interconnects and speaker cables! Raw material cost for top grade cable and terminations is currently $215:

5 1M interconnects
1 3M interconnects
2 3M speaker cabs

These cabs will compete against Nordost, Audience, Audioquest, and Audio note cabs currently being used. 2-3 weeks the solder should be done, very exciting.

I am constantly tweaking my diy speakers with my minidsp, and have just got some lengths of Nordost Flatline speaker wire and am about to get started stripping it. It's not going to be easy!

With regard to the minidsp, what sort of amps do you use for the active amplification? Can I use multiple integrated amplifiers even if they might not be ideal as opposed to power amps?

I've had 2 boards sitting around for some time and I am interested in trying them out without sinking much more into it.

Thanks

Another pair of speakers. Weather and time permitting. No rush. Loaned out the last pair and in order to get them back, got to give them something else. Would feel guilty making them go back to those entry-level old Maggies. Compact, relatively inexpensive towers with five 5" Dayton DS135's per side. In the cabinet assembly stage. Early tests were fairly promising but, in a sealed test box, bass limited.

Power cable using Beldin 19364, easiest, huge success.

Interconnect using Mogami star... result's mixed.

Speaker cables, forgot what I used, I think Mogami also.... failed (well at least I don't like the sound).

TT wall mount using cheap wood board and L-arms from home depot, doesn't look very good but sounds amazing.

Recently, just run in-wall speaker wire for my living through HT through basement. Haven't tried the actual sound yet.

Thinking of pulling dedicated power myself... that'll be my next project.

Amp stamds, no nails, made from fir, brass toes and stained then lacquer. Thinking about producing these and selling. Love the improvement its made, and looks great too. This one weighs in at 30ish lbs 1 x3's used. Dimensions = 22 x 22 x 3

I love 19364. You should consider trying 1312A or 5T00UP for the Speaker Cables.

This is the kind of thread I can relate to.
I used to DIY all sorts of things but as I got busier with other aspects of the audio industry I've found less time and I find I'm relegated to providing parts & pieces to those who are into building their own.
However, although the DIY community out here was strong at one point, it has faded over the last few years. (Must be all that oil/gas money guys are making - so they're just buying new gear! :shock: )

DIY anything audio can be a very rewarding experience, can cost very little and the learning process is very much worth the time and effort. So even if you eff it up it's not like you need to run to the bank for another loan.

I am building a phono stage for 78 RPM use. It will feature 7 selectable low frequency equalization settings and 7 selectable hi frequency equalization settings in an effort to match most of the equalization settings that were used by the different manufacturers.
