Each amp box had 3 350 WPC amps in it as well as forced air cooling, and with one guy on each side they were ball busters to lift if you had to lift them.
#STEREOTUBE AMPLIFIERS PRO#
Back when I did pro audio we biamped and we had amp boxes for the bass cabinets. Now with switching power supplies and class D amplifiers the power to weight ratios are downright crazy. Both required power transformers but the tube amps also required output transformers. Even if you don’t count modern switching amplifiers, and just count transistors, the physical size and weight difference is very significant. The junk gets binned and the better stuff gets handed down.Īs far as the size.
What you don’t see is all of the junk that was manufactured “back than” that was junk that fell apart. When you deal with antiques you are tempted to say they built things better back than because the build quality of the specimens you see are better. The thing is most of it has been disposed of by now. First off, there was a lot of tube stuff that was low spec and did not sound good. Posted in digital audio hacks, Repair Hacks, Teardown Tagged audio, grundig, restoration, stereo, The Post Apocalyptic Inventor, tpai, tube, valve Post navigation If you’re interested in the design of tube amps, we’ve covered heaps of cool builds: from this low-voltage design to this tiny guitar amp, or even ones using tubes which are flat. It looks great, though there’s always the option to use a cake tin instead. The video after the break is well worth a watch (we always find ’s videos entertaining).Ī new chassis is created out of a steel base plate and aluminium angle, and some neat frames for the motor transformers are made from scrap copper wire bent and soldered together. There’s also an integrated capacitor which contains three separate electrolytics. Firstly, an integrated motor transformer - an induction motor whose stator acts as the magnetic core of the transformer responsible for the tube electronics. The teardown of the original cassette recorder yields some interesting parts. was able to salvage the main power amplifier from one of these models, and restore it so that it could be re-purposed and see use once more. What’s more, they frequently sell on eBay for 1-10€ in Germany. The idea came when he realised that the TK 125 tape recorder manufactured by Grundig was still using tube audio in the late 60s.
has built a stereo tube amplifier in the style of the Fallout video games. However, the price of buying one to find out if it floats your boat is often too high to justify a purchase. Regardless of the debate on whether or not tube audio is nicer to listen to, or even if you can hear the difference at all, they’re gorgeous to look at. Many of us have aspirations of owning a tube amp.
