![]() ![]() You do not need that much high voltage rating, 100 Vce is enough, I have used TIP31C in a pinch and they worked very well, both in peavey and Music Man amps, and they can pass all the current 2 or 4 6L6 can need, think almost 1A peaks.Ģ) there are *grid driven* amps, where you have to handle way lower current, only a couple mA, but high voltage, hence the 350V rating, transistors are used like a conventional Long Tail Phase Inverter, replacing the typical 12A*7 used there.īOTH TRANSISTORS ARE INCOMPATIBLE so please check *how* are the 6L6 driven: through cathode current or in the conventional, grid voltage way.ĮDIT2: your transistor labelling suggests it´s the grid voltage driven one, BUT maybe a former Tech (or the Musician himself) replaced it with the wrong type, because he looked at the PV list and grabbed the first one he saw, BOTH are labelled "Tube Drivers" but are very different. Its got a lot of shorted output transistors. EDIT: notice that there are two DIFFERENT ways Peavey uses to drive power tubes, with completely different needs, both are NOT interchangeable.ġ) there are *cathode driven* amps, in which case you should use the MJE-15030 I suggested above, based on schematic. The MPS6530 cross referenced to a 2n3904 transistor which is available at Radio Shack. 1 Peavey cs1000x transistor equivalents 10-15-2010, 05:39 PM Hi, Im repairing an old Peavey CS1000x. ![]()
