 [Imagine my replying with a timid smile and total embarrassment.] Um. Well. I had to Google his name to find out who he is.  :oops: This just goes to show how fresh off the boat I am in the audiophile world. Half the time I see this or that poster's name, I simply don't recognize who he/she is. It's almost as though I had lived in another world until recently.  :wink:

Mr. Modjeski, I would be honored to learn from you whatever you can teach me about amplifiers. I will try to be a good student. :thumb:

RAM - this is a very thoughtful and highly cool endeavor you are proposing. I would love to participate, but dedicating 10 Saturday mornings isn't going to work with my calendar at all.

Now if you were to record these 10 sessions and offer them out to people for a fee so they could view them at their leisure I would be the first to sign up. In fact, I bet you would likely get 5x the number of interested people subscribing, which should easily cover the cost of filming and hosting the vid's.

Just a thought. Thanks for offering to broaden our knowledge of the design and build aspects of this hobby.

Bob

As I'm in Australia I definitely endorse what Bob said. Please consider recording lectures as I'm sure there are many like myself who would be happy to pay for such a service.

Thanks for your votes, responses and Personal messages for enrollment (which I will answer soon). We are close to having enough people so I hope to finalize enrollment soon. I am looking into a way of making the classes available to those who cannot attend live.

Roger,

Most of the students are novices and safety should be of primary concern. The supply voltage is in excess of 350Vdc and DIYers must take special precautions.

I recommend you include at least 1/2 the lesson on how to deal with high voltages e.g powering up, voltage measurements, etc.

BTW your idea of Amplifier Design classes is a good one.

Cheers.

Is anyone familiar with what ted_b used to record his talk about computer playback?  That might be an option.

Fantastic...  I received my Signal Generator today.



Next up is an oscilloscope.

I see an HP 175A tubed oscilloscope for sale locally for $30 with some other goodies.  Is this a good model or should I wait for the recommended hp 200 or newer?

Thx!

I picked up this oscilloscope for $50.



Will be testing the signal generator with the oscilloscope and vice-versa.
