Hi tweakers, My power amp odyssey has ended ( 'cept I still gotta sort out that right channel.) and it "will be" a fine amp, IMHO. The days of kits have...
RFM wants to acknowledge a few of those who helped in various ways with the recent power amp build project. 01) Jim Rivers, the founder, grand exalted poobah...
The right channel has been fixed!!! A slothful tech in RFM's workshop had soldered in a 2SA-798 dual PNP where a 2SC-1583 dual NPN should be. Has anyone...
Hi Jim, There's something familiar looking about that work bench. I think I've seen it before but it used to be busy. It sure is neat but me thinks its owner...
Ok, I've finished! And installed this "trio" (the amp with a couple of fine full-range mini bass-reflex) in my parent's house. Sound is really great! Very...
Hi Fabio, Congratulations on success with a major D.I.Y./tweak. Can you give us breathlessly awaiting, overly curious types a bit more data/specs? By ...
Ok, there you are: power amps are a couple of single-end (of course classA) solid state amps: just two stages a fet common source voltage amplifier and an...
The project power amp is running fine and sounding good. Would RFM put forth a biased opinion? 8:-)) I had promised the generous transistor donor, Mark Wilson,...
Hi Ray... Want to walk on the edge a bit? You might try putting a pair of MJ21195/96's in parallel on each channel, since your PS seems to be large enough, and...
Hi Mark, Ol'RFM has been to that edge and well beyond. 8:-)) The boards I used actually had pads for parallel outputs. The amp stack in Ray's room show a few...
I've enjoyed my large, heavy 42" CRT based TV for several years now but the sound from those small speakers leaves a lot to be desired. The big plastic case...
Cool. Hey LarryO, You make some caps using Vaseline and I'll make some with paper. And we'll see which are better. I bet yours will sound messy! 8:-) jim... ...
OK, youse guys make yours from vaseline and paper. RFM's gonna try the outstanding, K = 1.03, styrofoam. Finally, a use for all these damn packing peanuts! ...
My wood working pal Ken V. started this while wife and I were in Florida becoming grandparents!. I finished up temporary external crossovers, wired them, etc....
Hi Jim, Those are some impressive looking line arrays. Lines have a reputation for outstanding imaging....but these...just what IS with that center image?...
The line arrays just keep getting taller. These are GR-Research Alpha LS. Maybe 6 feet and weigh between 200 and 250. Oh, and sound good too! 8:-) jim......
Hi Jim, Just a thought...perhaps you should swap sides putting the tweeter arrays to the inside. I only say this as I can see the center image, though now...
They sound glorious. This room, always my 'second' system may now be my first. I want to listen a few weeks with the tweeters this way [mfg recommended] then...
Hi, I have 2 x Yamaha CT-810 tuners. I am interested in tweaking at least one ( and maybe both) as they were described on the Tuner Information page. I wonder...
Doug, You are more likely to find the info you want if you post this in the fmtuners group. You might also want to make clear what your goal of modding your...
