The cheater amp of which Haemphyst was speaking of was the Lanzar OptiDrive 50C Lanzar went out of business shortly after making that amp. The company was bought by the same people that brought us Pyramid audio equipment in the 80s. I just went look at this OptiDrive Plus 50. This is a current or nearly current piece. You do not have the amp Haemphyst is speaking of.

LOL, really? Yes, I know of the 50C. It is twice the size of the 50. However, the 50 is no where near a "current or nearly current" piece. This amp looks exactly like the 50C, just smaller without the C. If you looked both of these amps up, then you would know this (ampguts.com). I bought it used in 1995, that makes it at least 15 years old. That is not "current" by anyone's standard. Also, this is not the first time that I have been told that this amp is/was also consisdered a cheater amp.

Sorry, I did a search for the amp and the pic I came up with was of a different amp. It was a newer amp.

Is this your amp?

Yes, that's it.

And on the net (with the exception of few people who slightly remember them in random forums), that site is the only place I can any info on it....and other than the pics, it doesn't really tell that much.

That is not a cheater amp. That amp is capable of driving a 2 ohm stereo load or a 4 ohm mono load. A single TIP35C and 36C per channel. 2 power supply transistors, I do not remember if they were BUZ11s or if it had IRF-Z40s. I do have the 100 watt version. It has twice the output and power supply transistors. It can be for sale.

Ampguts says it can handle low impedences and do MUCH more power. Do you know how low it can go? 2ohm mono? 1 ohm mono? lower? I have alway been afraid to try, don't want to fry the best amp I have had. How much can yours be "had for"?

Are you sure that they are not talking about the 50C? The amp you have will not run long at any impedance under 2 per or 4 across it.

Straight from Ampguts.com

Lanzar OPTI 50

2 x 25W @ 4 ohms

2 x 50W @ 2 ohms

1 x 100W @ 4 ohms bridge

Reports say that can handle low impedances and do MUCH more power

Has pics.

Lanzar OPTI 50C

No info, but lots of pics so models not confused

When you find out how low it will operate, let us know. If you need my shipping address, just let me know.
