dreamie 0 Report post Posted August 30, 2003 As above. Wanna build a OTL amp but i'm afraid that the impedence, if not matched, will damage the tubes and circuit. What do u guys think? Share this post Link to post Share on other sites
Mackie 0 Report post Posted September 1, 2003 Impedanzer is the answer. Refer to Audio valve RKV head amp. Share this post Link to post Share on other sites
Tenson 0 Report post Posted September 1, 2003 How does it work? Is it just an impeadance matching transformer. Or does it work with that RF carrier technique? Or something else? Share this post Link to post Share on other sites
Mackie 0 Report post Posted September 2, 2003 (edited) I'm not too sure myself but in the Cayin and RKV, they both use impedance matching transformers. Edited September 2, 2003 by Mackie Share this post Link to post Share on other sites
Northern Oak 0 Report post Posted September 2, 2003 RF Carrier Technique? Not too sure if you are referring to the RF signal being modulated onto the carrier signal for the above ... IMO, I think it's just an impedance matching transformer. IIRC, the RKV's Impedanzer circuit is simple and sweet. Share this post Link to post Share on other sites
Northern Oak 0 Report post Posted September 2, 2003 Impedanzer is the answer. Refer to Audio valve RKV head amp. Correct me if I'm wrong here but having the Impedanzer means that it's transformer output, no longer a OTL amp, right? RKV -> OTL amp RKV+Impedanzer -> transformer output amp Am I right?

Northern Oak 0 Report post Posted September 2, 2003 Just to increase my post and to clarify something here : The design of the impedance transformer in the Cayin and the RKV's Impedanzer is 99% similar (1% short in case I'm wrong, hee hee hee kiasee). In other words, they are almost exactly the same circuitry. Share this post Link to post Share on other sites

Northern Oak 0 Report post Posted September 2, 2003 Which is? Any detailed description? It sounds interesting ... Share this post Link to post Share on other sites
Tenson 0 Report post Posted September 2, 2003 I don't have a clue!! But if you find out let me know! If you read the review for the MicroZOTL it has a little info on it. http://www.enjoythemusic.com/magazine/equi...0/microzotl.htm Share this post Link to post Share on other sites
matbon0013 0 Report post Posted September 2, 2003 (edited) To my knowledge the 'Impedanzer' is an output matching mini power amp (which is basically a transformer of some sort), no? As to my understanding it can drive high efficency loudspeakers and difficult headphones too (as in variable output), no?? I'd like to be corrected on this, thanks Edited September 2, 2003 by matbon0013 Share this post Link to post Share on other sites

Fine analysis and I do concur. In which case, I reckon Tension has to come to terms with the various cans he like and draw a conclusion on the impedance to match for his project amp. An outboard impedanzer will have to applied for cans of different impedance. Share this post Link to post Share on other sites
