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 don't recommend any tube scopes as they are a lot of work to keep going, big and run hot. If someone gives you one for free and it works,  then use it.

Looks good Martin, but the top of the wave should be thinner.  Try adjusting the focus and astigmatism.

Ivardlr2011,

As far as I know it hasnt, send Roger a pm so he knows, running a business means he doesn't live on these forums...

Chuz,

Drew.

Hi:
About six weeks ago I threw my hat into the ring, but have received no response about the status of the class. Was this for real, or was it a simple poll to gauge interest? Please let me know what is going to happen with this great opportunity.

I am sure when Roger is ready he will let us know the details. He has taught these types of classes in an bricks and mortar academic environment so I am sure he would want to prepare a curriculum that can now be morphed into an online environment. Not necessarily the easiest thing to do given that we have a mix of people with varying degrees of knowledge.

Not to mention Roger also has a lot of other things going on and I am sure he would like to have a personal life so his time is limited as such.

Nicely written Clio09, am looking forward to it, still sorting a signal generator!

Tis not the easiest thing to sorting out info such as this.

Looking forward to some learning!

Chuz,

Drew.

What's a 'chuz'?  'Cheers' with a British accent?

Gday Ericus,

Close......

We have what we call Kiwi's in Australia,  they are of course from New Zealand, they have a native race called the maoris, funny people mostly, thet have several sayings such as "beached as bro" and "chuz bro", which is cheers as you pointed out. I use it cause im a lazy typist, which probably stems from the aussie method of shortening all speech as much as possible but still talk quite fast, this is to reduce the number of flies one swallows......

Chuz,

Drew.

To me, it says a lot of good things about a nation's people when they are willing to poke fun at themselves. When I consider the current state of Canada or Australia, I can't help but think that, even if we had lost the Revolutionary War, we (USA) would be a contented people as part of the Commonwealth. Of course the world would not have had our successful republican experiment to grow upon. Hey! What does this have to do with building amplifiers? Sorry.

Thanks for the explanation, Drew.  I will now read all your posts with a very heavy Bill Hunter-esque accent!

Be patient my friends!  If Roger says it will happen then it will happen...though delays are quite common in these parts....

Just a WAG on my part...
but Roger has expressed an interest in having a school/shop/clinic/site the N-Cal Bay area Berkley.
Where amplifier design & speaker design could be mentored & perhaps some construction.

the online classes previously mentioned woulda been a logistical nightmare and fraught with
the opportunity to freeload.

imho....

Looks like Roger will be taking over the Randall Museum classes in January so that would be the class format for interested students.
