Quite a few folks who own Scott Nixon DACs, locally and around the web, have asked me if I worry about them always being on. I never did but decided on a...
I'm in a position of having to replace a couple of the caps in the PS on this tuner the filter cap is leaking and one large disc type cap has been abused........
Man, you can't rely on those FM tuner dudes! 8:-) Actually, the trouble is there may not be that many who have owned, gone through and documented an 8500 II. I...
If anyone at all is interested, I finally got a hold of a schematic for a cute little LT425-T I picked up to play with. (Thanks to Steve from Audio Asylum)...
Thanks for sharing your nice project... Looked at the schematic and I would also consider C327, C328 for replacement Also the ua703 is the oldest RF IC out...
This is a fairly new group - I just joined it from a link I found on the FM Tuner group site. I like AM radio for one thing - I live in central Michigan, but...
Hello Roger, Welcome to our friendly little site. Central Michigan is OK but on the wrong side of the bridge. 8:-)) Yup, I am a Yooper. A "long" wire strung...
it's best to use a 300 ohm ribbon downelead fro am just twist it, you attach the 'random/long wire on obne side leaving the other side free. if you want to...
Hi Ray, Love the UP. I've been up there many times XC skiing - the best snow and ski trails in the midwest! Good people up there too. Yeah, the Pioneer...

Hi Folks, My name is Christian Pruks, I'm from Brazil, and I am more of a tweaker than a DIYer. Most prices of equipment and accessories in audio these days...
My solid state amp has several 1N4004 or is IN4004 (not clear) , do any of you tweakers recommend I swap these out? or is better to parallel a cap across them...
Well, my opinion is that it depends on whether those diodes are used for power supply rectifiers (in that case swap 'em out), or if they are used for setting a...
... There is 4 of them in diamond shape (i.e. bridge) right after the mains transformer. There is two more near the 7818,7918 regulators. Here they are ...
Those would all be candidates for soft-recovery replacements. As for the bridge, you could also go with 4 discrete diodes of suitable volts and amps if you...
I've been trying to build an AM loop antenna similar to one I found at a DIY Loop antenna site to help reception for the AM band on the LT425-T tuner I've been...
Hello Robert, I certainly hate to bear bad news but I fear the vari-cap in your photos will not get the standard AM band when used with a typical DIY loop....
Hello, Thanks for the reply and the link to the site to buy the vari-cap. I put in my order, and hopefully it'll arrive in time for Christmas. I haven't had...
Hi Robert, Your luck is about to change for the better! As I type this I'm listening to WSM, Nashville, Tennessee from the U.P. of Michigan with a 3' square...
Well, I've finished up upgrading the caps in the practice Lafayette LT425T, and I feel I may be ready to try some improvements on my Pioneer TX-9500. It...
I'd like to try using Dynaudio 24W100 woofers with the R-45 ribbon (one woofer & one ribbon per side). The enclosure will be ported and about 1.6 cubic feet...
Thanks for the tip, I have posted the same questions there and on the Asylum page. Brian ... From: budandfun To: diy_audio_tweaks@yahoogroups.com Sent: Sunday,...
I've been doing some mods to a Sansui TU-217, and thought I'd share the progress and a photo. I've made most of the mods that Jim wrote up and shared on the...
One very worthwhile - and relatively inexpensive - upgrade I've done several times (for myself and for friends) is to refresh the sound in vintage audio...
For a little more expense, I prefer the Northcreek Zen caps to the Axon/Solens. Also, they have 100uf and 200uf models that sound nice... big beasts, tho! Of...
