Finally an electro-acoustic amp with a big HP! I have always had the nostalgia of my Carlsbro Sherwood 120 w with its HP of 15. And there, it is almost with a true breath, trunk, depth. The amp is also indicated by a good ease of use and adjustments quite obvious. No background noise, either.

The sound is convincing with a beautiful roundness, depth and a clear decomposition of the sound spectrum. The effects are not spectacular but they ensure to the required level. A rational construction that inspires confidence and even a certain aesthetic completes this overall picture. In the end, a sure value of type 'force tranquille', a great classic with a touch of modernity.
Hi all I have a little problem with an old amplifier with a resistor has blown and I do not have a diagram of the amp as it is an old guy. It is a Kustom MODEL quard 65 DFX Serial 0423 to 002,348 from Koustom Mucical Amplification INC Cinninnati Ohio USA Designed in the USA but Made in China. Resistance is on the PC card (power out to the speaker) a small board and the opposition have part number R24 In addition, there is a slight pipe tone when it is switched on, believe that it has been set to the wrong external speaker it comes from a school. So if there would be anyone have a repair manual about how I would be happy to get a copy so I can see the value of the resistance, it is only an attempt when the power out perhaps is burned, it is defective also goes it for scrap. / fb Flasherly 15:15.

Of course a shop-type person through experience should be able to examine the circuitry for determining a suitable replacement, provided that's all that went wrong. Martel 16:02. My prediction: You will replace those parts and they will burn up again almost immediately. I can't be sure without seeing the schematic - if it's in digital form, you can e-mail it to me at t u b e s @ p r o d i g y dot net - but those two parts may form what's known as a high- frequency load, a circuit commonly placed from output to ground in solid-state MI (guitar) amps. If that circuit fried, it has almost certainly done so due to ultrasonic oscillation, which will have occurred elsewhere in the amplifier. The parts you found fried were a symptom, not a cause.
E me the schemo and I'll take a look. Lord Valve Expert (like it or not) skibber 13:23. As I suspected, that circuit is a high-frequency load on the amp's output. These loads often burn up if there is ultrasonic oscillation present to any significant degree.
Your amp uses a power IC as the output stage; this is common with many of the cheaper Chinese amps on the market, regardless of what brand they are. There may be a fault in this IC which is causing oscillation, or the fault may be elsewhere in the circuitry. An oscilloscope and a test load will be required to chase this problem down. Unless you have plenty of experience working on this type of gear, you need to stop messing with it right now and take it to a tech. Bear in mind that if the problem is hard to find, a pro tech may well charge you more for the repair than the amp is worth. Get an estimate.

Lord Valve Expert This was the same type of thing that happened when all them neat & swifty 'Dean Markly' era amps 'designed' with power IC output stages came out. Cheap, plug in, sound like puke. Kaman found out the hard way when they bought DM, it took the right folks to fix them. Same as those Sunn Beta stuff. The tech either knew what CMOS IC had to be boinked, or the whole thing fried. VERY bad designs.

Things have gotten better now, but it's the same old story with the same ol' song.and I've been here so many times before.with the same old??? And the same ol' doors. (yes, lyrics are c/righted).anyway.Kustom at least is real good about making problems go away, they support the product, and they care. JJTj '.I'm the Hare, and I'm NOT the Turtle.'
