Randy Slone 6.6 design

py · 25th January 2005, 07:23 AM

I was planning to build the 6.6 amp from Audiophile Project Sourcebook of mr Slone. I would like to know if anyone here have already built this amp? I know it's kinda similar of is 11.4 amp from High Power Audio Amplifier Construction Manual but there are a few differences. I would like to know if anyone have ever heard this amp? How it sound? I would like to know if anybody ever constructed it so I could talk to someone about particularities of it (power supply design for example)... I will probably also modify a bit the design by constructing the speaker protection circuit on a separate pc board with an added clip detection circuit. This is my first DIY project but I am currently studiyng electronics so I am not completly unaware of many aspect of the project!

Need to talk to someone who's already familiar with the amp!

Hello,
Im building this AMP right now but have a few questions about some of the parts listed in the design. partly because the book I have has such small writing that its almost impossible to make out a couple of the transistor names. Plus the circuit layout isnt correct a coupel of the components arnt even listed. I will hopefully get the entire project done in the next few weeks. Will let you know what I find. thx, ryan

I found this kit, but I don´t know what version x.x it could be

Mosfet Power Amplifier

Any comments and experiences with this one are very much appreciated

...... two years ago I have layout PCB for mosfet lateral , schematic 11.4 if I remember .....

Could you post the circuit? I do have the book High Power Audio Amplifier Construction but not the one that you refer to. It would be interesting to compare the two circuits.

..... Schematic refer to fig .11.8 from book .....

Before we get too confused, I should mention that Figure 11-4 uses bipolar transistors and not MOSFETs. Here is the circuit.

....yes you are right , I have layout PCB posted here acording to schematic wich I have attached . PCB it's not for bipolar not for fig.11.4

Regards Alex.
