Arcam alpha 8 amp keeps blowing fuses - Audio Players & Recorders

See if the Speaker is blown or check for fuses on the back of the amps. Next switch the speaker wires at the back of the amp. Still no change? then switch the amp to aux input . Put a RCA jack in the aux input, then turn it on. Tap the end of the jumper wire with your finger tip , and check if you get a hum out of the dead channel if you do not then touch the wire to the metal cabinet of the amp. Check for a hum. If so then the pre-amp or tuner amp is not working. Good Luck, Bill

Best part of $50.

Fuses blow like this due to an overload. The cause being a semi-conductor such as an IC or transistor acting like it was a piece of wire. The most common cause is a shorted output transistor(s) in the main amp. But the power supply can't be ruled out. If you have an ohmmeter then a shorted device will be easy to spot. As it will be just like you have touched the probes together when a part (even in circuit) is tested.

Replace the loading tray belt, it is quite a common problem on CD Players using the same Sony transport mechanism as your Arcam.
The belt loses its tension and cannot fully load and then spits the tray open.
When you try to load a CD you should be able to hear a whirring sound after closing the tray and that's the motor trying to lift the laser mechanism at full travel but is unable to hence not enough tension on the belt.

Hope this helps.

hi,
I have the service manual of ARCAM AVR 200 with me. send me a mail on my mail id. I will send u the service manual. its a large file having a size of 4.8 mb. I can sent it through fixya.

Check the standby transformer T752 first. if its primary winding is short the this problem can occur.
ok

Hi -

Sony CD player Red / White RCA - > CD input RCAs on the Arcam.

From the Arcam Preamp Output RCA's, go to the Bose "Input". From the Bose "Output", you need RCA splitters to make them into four outputs to run your amplifier connections.

Check for bulging / leaky capacitors on the main PCB, they are a common problem on Arcam CD Players.
There should be a few 25v 1000uf caps scattered around, check those first.

Hope this helps.

Check the Arcam site for FAQ's on the unit.

Call them and find out if there's a factory reset method

A better solution is like I have mine; use the Arcam 10 connected to the tweeters of your speakers & the power Amp connected to the woofers & link the pre out's on the 10 to the power Amp. using phono cables. The Manual can be downloaded from Arcams discontinued section of their website.
This Bi-Amp method gives a far superior sound than just using the 10 as a pre Amp.

I would guess that during the move, the speaker wires crossed and smoked one of the output amp sections. The output transistors are shorted and are causing the fuse to blow. If you can post hte model number, I'll try to get you more specifics on the parts that will need to be replaced.
