    Can I plot amplifier frequency using Room Equalization Wizard? It seems to be a microphone based application. I would need to go about the process differently for accurate measurements.

    Not sure if anyone is interested in old tube amp restoration? But here is a project that I am working on. Its a vintage 1960'ish Heathkit AA-100. I got it as a non-working project. It now works well and just needs some minor clean up on some previous repairs. It sounds great!! So far I have not...

    Hello! My name's Cody; I work for TARA Labs. Not here to promote anything, this is just a disclaimer. In my experience, I have found that tube amplifiers and pre-amplifiers offer a more musical sound – in the sense of resembling live, accurate, un-amplified music. I receive many comments from...

    Is there a you tube video explaining how to use REW V5 in room acoustics measurement? Also, how to interpret the results after tuning the room and calibration of speakers in 5.1 or 7.1 ? Thanks very much.

    I'm new at this, but I'm old school at heart. Where would one start to build a 50 WPC two channel tube amp? I'd like to keep the cost under $400. BTW, I know very little about this, but I'm one of those people who learn by doing. So at the very least, I'll know what I did wrong.

    Yes, I am trolling. I've been trying to learn as much as I can about audio electronics these last few years, and have built some tube audio circuits that I've decided are keepers. I started back in the 1980s with mainstream 'good' solid-state gear, worked my way up to a complete Audio by Van...

    The Jolida Fusion JD-3502 Integrated Tube Amp was introduced a couple of years ago at Rocky Mountain Audiofest and was again shown at RMAF in 2012, but has only recently been released by Jolida (Maryland). You won't find any info on Jolida's site at this moment, as they have only furnished...

    I am back on the two-channel ban wagon again. I am about to go through a speaker evaluation pretty soon, considering several different speakers. I am looking for the right tube amp for that evaluation. After hearing all the various tube amps at LSAF, I am sold on giving tubes a go in this...

    Here is how all the pieces went together. The preamp is stacked on top of the phono pre. The 2A3 SET amps are on either side. With high efficiency speakers, this is a very warm and detailed sound with a beautiful midrange.

    Here is my version of the Dynaco ST70 tube amp if it were built today. The only original Dynaco parts are the output transformers. I changed the layout a bit and used more filtering in the power supply section and better parts through out.

    Recently I have been thinking of integrating a tube preamp into my system. On the list of preamps I have been thinking of using are the Rogue Perseus and the Cary SLP98. Both of these preamps come with a home theater bypass which can be used when the preamp is off. The manufacturer states that...

    Hi Everyone, I'm new to this forum and noticed that people here seem to know quite a bit about speakers. So here's my situation: I have a soon-to-be recapped and fully restored HH Scott 299C tube amp that's going to be looking for a nice set of speakers for a home audio set-up. It's a 30 watt...

    Is there any advantage of using a DAC with a tube stage when I already have a tube preamp?
