    I think its odd that both units have failed.  Hopefully its simple fix.  Sign up at Hifiengine as it appears they may have a schematic.

    I was thinking the same. I think they have sat unused for a while, both seem to have leaky capacitors. No smell or signs of any burning. I guess I'll get them to a technician to check over.

  2. I have an sta 2000 that I use in my shop, I've always found it a very pleasing amp, with plenty of power. I think the  75 Wpc is somewhat conservative. Manufactured by Foster apparently.

  3. Hi all, I'm looking for a budget friendly headphone amp to power a pair of vintage AKG k 340, I've owned them for years but never got the best out of them, due to their need for more than just the regular headphone out of most receivers/amps. The choices for amps are mind boggling and somewhat confusing to me, anyone had any experience in this area? I believe the k340 are 400 Ohms. Thanks.

     

     

  4. If you want to understand the science behind global warming then start by studying the science...easy huh?...Unfortunately, and more often than not, Americans take more heed of the politicians of whatever party they subscribe to, or to their pastor...That is an ***-backards way to approach the subject. Have a chat with your Alaskan brethren, have a chat with the Inuit, or even better join me when I next go on a photo expedition to the Artic. You can argue the causes, though even that seems pointless, but you can't deny the fact that global warming is happening. If you do deny it, then you owe it to yourself to do some research of your own, by now you should have realised that you can't trust a politician, especially a republican, on this issue, and pastors don't generally like science.

    Chemistry Expert: Carbon Dioxide can’t cause Global Warming:

     

    http://principia-scientific.org/chemistry-expert-carbon-dioxide-cant-cause-global-warming/

     

    "Why on earth do we attribute any heating of the oceans to carbon dioxide, when there is a far more obvious culprit, and when such a straightforward examination of the thermodynamics render it impossible."

     

    "In a nutshell, water takes a lot of energy to heat up, and air doesn’t contain much. In fact, on a volume/volume basis, the ratio of heat capacities is about 3300 to 1. This means that to heat 1 litre of water by 1˚C it would take 3300 litres of air that was 2˚C hotter, or 1 litre of air that was about 3300˚C hotter!

     

    This shouldn’t surprise anyone. If you ran a cold bath and then tried to heat it by putting a dozen heaters in the room, does anyone believe that the water would ever get hot?"

    So, do you believe the sun has an heating effect on the oceans?

  6. I would have thought $100 to repair those speakers would be well worth the effort tom b. If by some chance you don't like them I'm sure someone would happily take them off your hands.....along with a tidy profit. I believe the 15TL was at or near the top of the heap at the time.

  7. No problem with the 30 watts of the Marantz, later on when the upgrade bug hits you consider having it re-capped and generally gone over. I have recently had two of my vintage Marantz receivers (2240 & 2245) re-capped and was knocked out by the improvement in sound.

  8. The whole world is laughing it's head off at the prospect of a certain reality show host winning the presidency of the USofA...It has also unfortunately reinforced the worlds stereotypical view of Americans in general...A sad day for America, and indeed for democracy itself...
