<p>pločica odgovara lijevoj APEX i ovoj šemi sa ESP120 koju je postavio samuki,samo što se kod te ESP razlikuje vrijednost otpornika i kapacitet/vrsta kondenzatora - sistem rada sve tri je isti. ja sam koristio ESP120 šemu zbog mogućeg sušenja elektrolitskih kondenzatora tokom dužeg niza godina,blokovi su imuni (-ji) na te pojave,jedino što bi morao da "prejašiš" dve rupe na pločici predviđene za dva elektrolita i tu postaviš blok.</p>

<span style="color:rgb(0,0,0);font-family:arial, helvetica, sans-serif;font-size:16px;">Remember that the crowbar circuit absolutely must never be allowed to operate with any normal signal. A perfectly good amplifier that triggers the circuit because of a high-level bass signal (for example) will very likely be seriously damaged if the crowbar activates. To verify that no signal can trigger it, you may want to (temporarily) use a small lamp in place of R2, and drive the amp to maximum power with bass-heavy material. A speaker does not need to be connected. If the lamp flashes, your amp would have been damaged. If this occurs, you may want to increase the value of C1. Note that bipolar electrolytics should </span><i>never</i><span style="color:rgb(0,0,0);font-family:arial, helvetica, sans-serif;font-size:16px;"> be used for C1, because they can dry out and lose capacitance as they age. This could cause the circuit to false-trigger.</span></blockquote>
