Yes,wuffwaff.
I saw it on Mark Finnes website, those white color rectangular thing that is giving me a headache.
I reside in Kota Kinabalu,Malaysian Sabah on North Borneo Island, famous for it's diving spots, turtle island, orang hutan sanctuary and mount Kinabalu, highest mountain(world heritage) in SE Asia. Her image is slightly tainted in recent years by Abu Sayabs in their kidnapping spree and 911 although it's generally safe here, no extremist activities here. Before I forget, my condolences to 911 victims of US and various nationalities. Majority of our tourists are Taiwanese and Europeans like to visit our natural spots. Hospitality is quite exceptable esp to foreigners. Should you ever visit this part of the world give me a call. You can get cheaper tour packages if you know your way around.
I'll try seaching MPC71 on the net to see if I can find any. I am told most parts here are of very low quality from Hong Kong, Taiwan or China.
Is it possible to check if the amp is oscillating or not with very very limited knowledge on electronics? Can I hear the oscillation on the speakers?
I've just received "Art of elecrtonics" and I am stuck in the formulas on capacitors and inductors in the first chapter and am depressed. I think maybe my dream of buildind a successful Alpeh 4 might vanished. I am worried.
Is there any website that anyone knows of that gives advice on basic electronics?
The DMM my friend use is fluke. I think he is the most extravagent repair man in town. He ask me to get a fluke because he says cheaper DMM from Japan cannot be trusted. I can't afford a fluke. I only want to built 1 amp and 1 preamp. I am think of getting a USD30 DMM once the parts arrived. Is it advisible to invest in a better DMM and around which price range?
Thank you Joe Berry for your tips. I will be building a 15v regulated power supply for mosfet match using LT1085CT and LT1033CT. I found the diagram on Sterephile website - Aunt Corey,s homemade Buffered Passive Preamp. I will be using this to test that troublesome 0.47 ohms resistors.
tiroth,
Do you mean that 0.5 ohm vishay is a good alternative?
I mean with reference to the sound. Should I just get the 0.47 xicon 10W to avoid any problem. Will it oscillate? Forgive me for asking such simple question as I am really stupid on electronics.
I actually wanted to built NP zen preamp. But it is not suitable for sensitive speakers according to NP in his article. I have my 2nd Proac response 2 speakers and it is very revealing( I think it is not amp friendly). I have tested the speakers on Holfi SE integreted amp and it sound very good. I think SE Aleph might be able to match this speaker. It's a risk I am taking. If only I can afford a commercial Passlab. I read X600 sound very good.
I have a 2nd handed meridian 506 cd player. I am thinking of building David Hurst preamp which I found on this forum to match with Aleph 4. Nelson commented it is a better zen preamp. Does anyone think it is quieter than zen? The other thing I am worry about zen is the variable in the circuit. I can't understand how to adjust it. I haven't order the volume pot from Michhael Percy yet for David Hurst preamp, except the transformer, same rating as Alpeh l preamp, only bigger ampere. What is your advice?
I will be glad if anyone can kindly point out resistors in Aleph 4 will have the risk of current operating near 0.5 watt power ratings.
Thank you.
