| When was the last time you listened to live music? To the original question: 'last night'.Years ago I used to do PA systems for special occasions, using a set of Fulton J-modulars for the speakers, tube amps and the like. People would ask me 'why did you lug all that stuff here if you aren't going... | |
| Mini Amplifiers Dynaco made a cute little amp years ago called the SCA-35, which was an integrated. They also made something called the Stereo-35 , which was the power amp section of the SCA-35. Both had nice output transformers and made about 17 watts per channe... | |
| Feedback blew my phono stage? Just to be clear there is no way any cartridge could make enough voltage on its own to damage a phono section. | |
| Joule-electra LA-150 Mk 2 dead There are not many faults that can cause tubes to not light. In this case I bet the old tubes were also white inside. If that is true, they lost their vacuum and its simply not possible that the preamp had anything to do with that, unless the sock... | |
| Amp Shutting Down, need help Sailcappy, has anyone recommended installing a current inrush limiter? This is a device (goes inside the amplifier) that when cold has a high resistance and as it heats up, goes to a low resistance. They come in different current ratings; for exam... | |
| Feedback blew my phono stage? David is right- you need to do something about mechanical isolation for the 'table.If the preamp really was damaged by something to do with the ground, then both the preamp and amps need to go back to Halcro to get the problem fixed. There is no w... | |
| Harman Kardon Pre amps The best HK preamp was the Citation 1 :) | |
| Balanced But Not Fully Balanced If the gear uses transformers for input or output, then it can operate fine in the balanced domain with no tradeoffs. But preamps with input or output transformers are rather unusual. Balanced operation was originally conceived to eliminate proble... | |
| Speakers for low power tube amplifier I am putting another vote for Audiokinesis- that is if you want bass along with easy-to-drive. They are highly detailed and very easy to listen to.If the room is very large you will want to consider horns- that is about the only way you can get 22... | |
| Joule-electra LA-150 Mk 2 dead Did the tubes loose their vacuum? Do they still light? What is the nature of the failure? | |
| Set amps ? The Response 2.5 works great with our M-60s, but as I recall some customers could run them (60 watts) out of power, although they were in a large room. 6-8 watts just won't be enough. | |
| Valve phono or valve linestage? which stage is providing the greatest contribution?Both of them :) However, if you loose detail and musicality upstream, there is nothing you can do to recover it downstream. OTOH if your line stage is not up the task, no amount of a detailed and ... | |
| Protection Kicking On At Low Volumes? If the amps are a little older its not that weird for the protection relays to develop corrosion and become intermittent, and especially not that weird if two amps of the same brand and model develop the same relay problem. The symptom would be in... | |
| Harmon Kardon citaion 1 kit telefuken We have repaired, rebuilt and modified many of these over the years. Its my favorite vintage preamp, and IMO keeps up easily with most modern preamps once refurbished.The electrolytic capacitors are all shot. Do not try to use them.The selenium re... | |
| Amp Shutting Down, need help If it has large toroids, there is no SMPS. A SWPS might look like an aluminum box inside the unit, but certainly would not sport any toroids, especially large ones. So the theories around SMPS are not.I still think its a good idea to try this amp ... |
