bluesboy Posted February 16, 2008 Share Posted February 16, 2008 Has anybody out there had any experience with Hagerman Technology phono pre-amp kits? I got a Bugle kit in the mail today. It looks like it might be a bit of a challenge to build. My soldering experience is limited to point to point wiring on crossovers. I've never done any circuit board soldering. Any suggestions?

Tarheel Posted February 16, 2008 Share Posted February 16, 2008 Why do you want to go messing around with something like that? Want to hear a good preamp come on over and listen to my QS Audio preamp. Its already soldered all up and ready to go. One more thing.....keep that bottle of scotch away from the soldering iron.

bluesboy Posted February 16, 2008 Author Share Posted February 16, 2008 I was hoping you would come by and QC the project. There won't be any scotch around unless you and or Old Buckster brings it with you. Quote Link to comment Share on other sites More sharing options...

Funny you bring this up. I bought one from a guy at A-gon for $50. I soldered it today with with bad results. Can't get a signal through it. I'm wondering if it's a bad switch. I bought it to practice my skills. All the connections are good so I'm at a loss. It really is an easy kit if you have a good iron and a little experience.

Tarheel Posted February 16, 2008 Share Posted February 16, 2008 Well I would but I am real busy deciding what equipment I will put in the new music room in my new house once I win the powerball drawing tonight. Thinking about those Ayre MX-R mono blocks machined out of 75 pound blocks of aluminum pushing a top of the line AR tubed preamp powering my three Jubilees. Stuck on the TT but thinking a VPI TNT with a Clearaudio Goldfinger might be nice. Quote Link to comment Share on other sites More sharing options...
Guest " " Posted February 16, 2008 Share Posted February 16, 2008 can you scan the assembly pages and post.....hard to weight in on it with out looking it over...I've done some complex circut board stuff over the years and can give some comments once I see the lay out.

bluesboy Posted February 17, 2008 Author Share Posted February 17, 2008 nu2tubes, Let me mess around with it for a while. Maybe I can figure out were you went wrong. One thing Hagerman mentions is the use of an ohm meter to test the resistors because the color coding can be confusing. Quote Link to comment Share on other sites More sharing options...

I don't have a meter, but I have a magnifieng glass and reading glasses for these old eyes[] I put it on the shelf for now. Going to look at it next week. I thought there might be a bad solder joint and I rechecked all of them , they all seem good. Quote Link to comment Share on other sites More sharing options...
bluesboy Posted February 17, 2008 Author Share Posted February 17, 2008 Are you saying the resistors don't come with a label or ID tag? Just lumped into a bag? Yeah, they were lumped in the bag. Hagerman does include a pretty thorough compoment table with a detailed explanation of what each of the color bands mean on the resistor. I just got my ket done a little while ago. I've got it soaking in alcohol for a half an hour which Hagerman recommends to clean up the circuit board. I'm going to let it dry overnight and try it out tomorrow. I might even post a couple of pictures. Quote Link to comment Share on other sites More sharing options...
bluesboy Posted February 18, 2008 Author Share Posted February 18, 2008 Here's some pictures of the assembled kit. Turns out it wasn't that hard of a project after all. I guess it took around three hours or so. I was tring to solder and watch the car race at the same time. I could do it a lot faster the second time around. As for performace so far so good. I've got the pre-amp hooked up between a Micro-Seiki DD-40 TT with a Grado Reference Master cartridge and my funny looking Kailin tube amp. So far the set up sounds as good or better than any turntable- pre-amp combo I've tried in my system. Not bad for $62.50 shipped. Quote Link to comment Share on other sites More sharing options...

Marvel Posted February 18, 2008 Share Posted February 18, 2008 They have some nice little kits if you like solid state and op amps. They have an A/C power supply you can get for the phono pre, which provides ±15VDC. Be nice in a small box. Maybe a chocolate box. Quote Link to comment Share on other sites More sharing options...
