Nice amp! As far as getting ripped off, the last time I was in Poland (1992) the prices seemed about the same as the USA or maybe even a little higher given the salary differential between the two countries. Needless to say my travel expenses while in Poland were very small in an absolute sense.

I don't LIVE in poland, I was born there. I live in the US. I just went to poland for vacation.

I mean, the prices there for things are really cheap. If you factor in salaries though, they're still cheaper than prices here. For example. I bought the case for around 75 cents(3 zloty).

Sorry to go a bit off topic, but prices in the Eastern Bloc went up just after the collapse of the Soviet Union and then came rocketing down (at least this is what I saw in Russia). For example, McDonald's was very expensive in the first few years of the last decade, but when I visited this past June, the prices were about 1/2 to 1/3 of those here in America.

Also, if you buy electronics and electronic equipment in regular retail stores, you may find prices closer to American ones. If you want good deals (in Russia, anyway), you have to go to specific markets. There's an electronics market, a building-supply market, and anything that you'd like can be found in the different markets (these are in the Moscow area).

Okay, now you DIY people can go back to your discussions

oh yeah, prices on electronics are wild all over Europe(well, Poland and Germany, at least). I walked over to tons of electronics stores, and walking out, I just laughed. Well, xept for my hd580s

Oh yeah, comments on the amp?

are you saying that you can get all the parts, including the op amp chip for under 5 clams?

if so, maybe you should look into importing (formally or informally) those opamps from poland. i'm sure you would have lots of takes on cheap opamp chips on this forum.

good for beginners who might fry chips in their frist projects....like me!

right now, they have the 2 big macs for a toonie special at macdonals in Canada... what's that, 50 cents US a burger

your amp looks great, do you have a volume control? I prefer a pot over the level switch as it allows you to use the amp from the line out, bypassing the crappy built-in amp

Nope, I don't have a pot. Would it be difficult to add one??? Oh yeah, the opamps in poland are about 50 cents each. . .

burr brown opamps for 50 cents? wow..

adding a pot is easy, you just put it between the inputs and the circuitry.

Well, since my amp is already built . . . would it be difficult to add one now?

Did you use OPA132 or OPA134? OPA132 is discontinued, so maybe that's the reason they sell them cheaper...

By the way, you did good, it's a nice looking amp, and the price is right too .

thanks! I used opa134s. They were aquired from a forum member here (ray?). But I saw them @ the store for 50 cents.

So, is it possible to add a pot now????

You should have all the detailed information about adding the pot in the Headwize project article.
