<DIV><FONT size=2>You can use 1N4007 diods to replace seleniun
recr.</FONT></DIV>
<DIV><FONT size=2>If you need more current use 1N5407 3 amp 1Kv.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>I have been replacing seleniun rect. for many years
.</FONT></DIV>
<DIV><FONT size=2>You may need a small resistor to drop some
voltage.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>I have lots of new old selenium and coper-oxied
rect.</FONT></DIV>
<DIV><FONT size=2>Most went bad with just age.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>After repaaceing check voltage and see if to
high.</FONT></DIV>
<DIV><FONT size=2>you could even use a small zenner diode in series to drop
voltage but watch current </FONT></DIV>
<DIV><FONT size=2>and make shuer what watt zenner diode is needed.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>you could even replace TUBE rect with 1N4007 diodes and small
resistor or zenner to </FONT></DIV>
<DIV><FONT size=2>keep output voltage to normal level.over voltage can dammange
tubes and caps and </FONT></DIV>
<DIV><FONT size=2>outher parts.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>Watch out for this when replacing rect. tube or
seleniun.</FONT></DIV>
<DIV><FONT size=2>Seleniun rect. have less V drop than tube and 1N4007 has about
.75.</FONT></DIV>
<DIV><FONT size=2>depends on load.Whatch out for this.</FONT></DIV>
<DIV><FONT size=2>Usually selenium rect has a + or red dot or red
terminal.</FONT></DIV>
<DIV><FONT size=2>On 1N4007 ETC. the band on one side is + out if AC on outher
side.</FONT></DIV>
<DIV><FONT size=2>If a B+ around 400V band on diode will go towards + side of
filter cap.</FONT></DIV>
<DIV><FONT size=2>This may be threw choke or resistor.</FONT></DIV>
<DIV><FONT size=2>Just trace your circuit.</FONT></DIV>
<DIV><FONT size=2>You should be able to do this with out a diagram.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>To make is easer drow it out on paper.</FONT></DIV>
<DIV> </DIV>
