Eddierukiddingvarese Posted February 15, 2017 Share Posted February 15, 2017 Yep, I think all these are included in the broader definition of shed- some where the wife does not go SWWDNG 1 Link to comment Share on other sites More sharing options...

Upfront Posted February 15, 2017 Share Posted February 15, 2017 Surely you jest Mr Horns. Well its definitely to place to listen to hifi. Storage on the other hand, is generally a different story. On the plus side, it leads to retsoration projects like this one! Link to comment Share on other sites More sharing options...
Stevesie Posted February 17, 2017 Share Posted February 17, 2017 (edited) Radio surgery time. Sony make great sounding radios, but their tuning caps are junk. Swapping one from a $6 eBay clone to get a few more years out of it. Edited February 17, 2017 by Stevesie 1 Link to comment Share on other sites More sharing options...

mwhouston Posted February 24, 2017 Share Posted February 24, 2017 This was the original 6L6 tube amp in a wine gift box. From this I built the far more improved model in the stained wine box. Listening to it now and love it. I had another crack at the original but with 12AU7 and JJ blue glass KT88s. Sounds excellent and dead quiet but I'm not happy with the PS. So tomorrow, once more, I'll alter the PS to the one I know works. It can us the tranni box or the second one (Silver Supreme). I have some black metal 6L6s which I'll drop in. For now here are some images with the KT88s. 2 Link to comment Share on other sites More sharing options...

When I get my finger out.... The ceiling is going to get ~4m x 5m, 300mm deep. Front speakers are going to be built into corner traps. Sidewalls, yet to be determined. Most of it (except the screen and speakers, of course) will have some sort of diffusion / reflection over it.... will require some experimentation. I did the obligatory "bring the entire stash inside, and chuck it anywhere" test .... and the result was quite dramatic for the LF. Link to comment Share on other sites More sharing options...

NADMAD Posted February 24, 2017 Share Posted February 24, 2017 My ALDI router table was too small, too inaccurate, and also wouldn't accommodate the 19mm radius bit I needed to round the edges of my ESL panel frames, so I built one using the legs and switch from the ALDI one, a sheet of laminated MDF and a Bakelite router table insert, with a bit of 2x4 acting as a fence! It's temporarily clamped in place but will eventually be on runners. At the heart of it is a 1980s 2hp Makita router.

Guest Posted February 25, 2017 Share Posted February 25, 2017 Having a go putting this 50w x 2 mosfet stereo amp together over the weekend quite a few holes to mark drill and tap yet. Replaced some poly fuse devices on the module with copper wire bridges on advice as it has speaker protection via dc offset main power input relay Link to comment Share on other sites More sharing options...

mwhouston Posted February 25, 2017 Share Posted February 25, 2017 (edited) New I'm happy. I have the whole PS issue sorted. Apart from simple tweak I'm happy with the whole. This one also runs from my universal tranni box. One set of two trannies wihich supply 12VAC and 250VAC. My stained box 6L6 uses the same tranni box. Saves about $100 a build. JJ KT88s and a Phillips 12AU7 make the tube compliment. HT is 320V and amd filament voltage is 12V. Bias is 22V on the 88. I have only had a quick listen for about 300mins and sounds really nice. Not sure it will top the 6L6 but nice to be able to amp roll using the same base PS. Edited February 25, 2017 by mwhouston 2 Link to comment Share on other sites More sharing options...
