Pioneer M5

[destroyer X]

I would like to have this amplifier schematic.

I am interested to assemble the power unit to listen to it.

Can you please, upload the power amplifier schematic or service manual to:

panzertoo@yahoo.com

thanks in advance by your kindness.

regards,

Carlos

I have a non complete schematic found at JA1MDN home page..not enough to simulate...i am still simulating but i see something was missed.

[destroyer X]

It is using tripple darlington into the output... also feedback seems different...also input stage.

regards,

Carlos

Hey man!....please!>..send this stuff to old uncle Charlie!

Hi Carlos I dont believe you want to try build this after you see the schematics, this amp is super complicated .

I dont have detailed schematics but Ill post what the front end looks like.

[destroyer X]

I have found this one... i suppose it is the M5 schematic.

This one is not complete...i have found it in JA1MDN site

Working with high voltage into the input.

Carlos

Are you sure your schematic is the correct one for this model?

I am not sure about mine..it looks to be...but not informed into the Japanese site....or i could not read entirelly..there are signs i do not understand.

If you can read perfectly the Japanese, go there, as i have only some basic knowledge about this language..alike others...only basic... at least i know several languages..all basic knowledge.

here you have the link:

and the schematic posted looks complicated (yours)..for sure i do not want that complicated stuff in my life..do not believe sounds better because complicated.... maybe the opposite...each part distoting and contributing to the final mess...that artificial lifeness sonic.

Here you have a text i found about it:

- "Monophonic power amplifier carefully finished from the idea "the amplifier for having a music intoxicated.

It returns to the origin of the amplifier design of amplifying an input signal faithfully and reproducing as an output signal, and the "new super linear circuit" which acquires a property without applying NFB is developed and carried. This banished TIM distortion from the origin and the stability in a high region is secured."

Notice the idle bias setting without VBE multiplier. Wonder how they prevent thermal runaway.

Observe here...this looks to be a VBE multiplier trimpot... the stand by current adjustment..not sure..but it is possible this adjustment exists into the complete schematic substituting some fixed resistance you have into the circuit.

Dear Carlos,

My fault I didn't explain myself good enough. I mean there is not VBE transistor for thermal compensation but just a simple potmeter.
