    Are you looking for an audio project to build?

      I was going to design something for members to build if there was any intrest. Or another member could design a project and I would be glad to help.

          Rob,

          Well here are some diy ideas

          1) Buffer/Preamp

          2) Interconnects/Speaker Cables

          3) Amplifier probably too complex

          4) something from DIY Audio forum

          What projects do you have in the works?

            My main project is putting a versa 'table back in service, nothing anyone but its designer can assist with. I have a cosmetic restoration underway on a pair of VTL mono amps, minor stuff like redoing the chrome and changing out corroded binding posts, etc.

            a basic buffered preamp with 3-4 line inputs and a stepped attenuator would be interesting, simple enough most people here could attempt it.

              Rob - keep us apprised of your Versa project. I had a 1.2 and a 2.0 once upon a time, but decided that simple was better for me.

                very cool. I had a 1.0 back in the day and did not find it intimidating or too complicated, it work flawlessly for me. My 2.0 is missing the compressor/box John Bicht is still around and promised to help me get the 'table up and running again

              Id like the plans/schematic for a 150 wpc stereo tube power amp for under $1000 in new parts including chassis. Is that possible?

                probably not. I saw an older VTL ST-150 on the 'gon for under $900, that's a steal for kick ass amp.

              How about we start with speaker wire or interconnects and we can follow up with some comparisons with commercial products?........before we attempt more complex projects.

                JC,

                to answer your question, here are some of the best tube kits I know but for the power you require you probably will have to spend twice your proposed budget

                http://www.tubes4hifi.com/bob.htm

                besides asking for that much power out of a tube design is asking for trouble for various reasons.

                  He should buy it if he is serious about wanting a tube amp of at least 100 watts for $1K.

                    I think that a good power line filter might be a good starter project for a lot of people. It's relatively easy to make, doesn't require a lot of electronics knowledge on the part of the builder, and has real benefits to the sound of most systems. Something that one could plug all those noisy wallwarts into that would prevent them from contaminating the power going to one's expensive components.

                        You don't need a remote - you need headphones!

                        The main website I suggest for all things DIY audio is surprisingly; DIYaudio.com. There are subtopics there on every facet of audio you can think of. The majority of them describe "one off" projects but there are many amplifier/preamplifier designs/discussions that a number of folks have decided to try building and have "chipped in" with PC board layouts (files) and even "group buy" collaborations. Of course, the main problem with DIY, especially electronics is corralling the necessary parts. Fortunately, the site has links to a number of vendors who provide parts / kits / etc.

                        Audioasylum.com has a few DIY subtopics. They have had discussions on cable building and power conditioning. Jon Risch made excellent contributions to those and his work can be googled under his name.

                        I've experimented with balanced power conditioning and found it to be worthwhile. PLEASE BE CAREFUL with any experimenting in this area especially if you play around with power line filter capacitors. There are capacitors designed especially AC power line use - I believe they have an "X" designation.

                        Have fun but keep the (solder) burn cream handy!

                        ps. akitika.com has a very reasonably-priced transistorized amp and preamp kit. Don't know who if anyone in the US (or Europe for that matter) is supplying tubed kits. There are a number of Chinese kits on the web have but have seen no feedback on any of them. Anyone tried any of these??? Recommendations???
