    Welcome!! Please leave a comment and I’ll quickly respond unless of course I can’t. This is just coming together today (11/13/2013) so will be a bit before I can get all the projects uploaded and displayed.

    Getting some of the projects up and documented. A few more to go! I also added a few more Tube datasheets and Hammond chassis drawings for boxes I have used in the projects. Remember, click on the buttons under the ‘PROJECT RESOURCES’ section of the article for more details or parts used for the builds.

    The site is filling out, added a slew of tube datasheets, some Dynaco manuals for the MKIII and ST-70 project as well as filling out the project stories. Still need to add some pictures to the ST-70 build, write up the Dynaco MKIII build and begin the EZ125 amplifier project. Moving along. If you need something that I forgot to add or need something useful please let me know and I’ll do my best to add it in!

    Added more of the Dynaco Mark-III project. Picture comments are updated as well as the order. Almost done with the project description, need to add a few thumbnail pictures and good to go.

    Check out the new EZ215 stereo amplifier project. It’s a great sounding simple stereo amp.

    Hi.. It’s great to see your done with pcb. Is it great for guitar? By adding Marshall tone stack maybe. Thanks, opik

      I have not done anything with Guitar style amps, but I think this would work very well for them. The PCB makes for a clean build and easy to fix. I have run the smaller amps every day for a couple of years and have no issues with heat yet.

    Thanks for reply, I’ll wait for your next guitar amp I hope 🙂 there are Cameron Ocean mod for jcm800 on youtube It’s amazing tone, compare to the regular jcm800,, are this grommes 260A can do the same thing? I need both for hifi and guitar, I want to hear your 260A sing, before I decide to build it, its look like the power went to 120 differ from my country 220, while commonly 220 is going to 110, not 120, anyway can you upload how it sound?..thanks Sandy

      I really like the sound of the 260A, I think it has room for a lot of modifications, but I’m so limited in time I have not done much with them other then listen. The best sounding amp I have built was the EZ215 stereo amp. I have built a second one with 6L6’s and with a little more B+ (only a couple more watts) but it sounds fantastic. For power it’s only getting the correct transformer, and I think 110-120 is not a problem. I don’t know really how I would do a sound upload as it would get lost with all the compression, but I do like the EZ260, it very smooth and has just the right amount of power to get loud. The EZ215 is _almost_ perfect in my book except it’s just a little low on power, but typically I’m not listening to music so loud that I can even tell. Both are fun projects. I’m holding on the JCM project as I had this crazy idea of building a digital clock out of relays… Don’t as 😉

    Right,,compressed audio will lose the sound and feel, I’m glad 110 will do. Hope this year I made my own G260 with el34. Keep your project post, I’ll wait your JCM version 😀 thanks..
