Does the average dude (or chick for that matter) get the fact that 40 year old output transistors are junk, and should not be trusted???????? Even if you run them on a transistor checker, it is NO Guarantee that they are going to handle the stresses of being inserted into a back plane of an amp that gets cranked on when the operator gets loopy on a Friday night. Transistor Checkers do not simulate real world conditions (serious amps are flowing through each output) and only tell you if the transistor is shorted or weak and gives you NO IDEA if the part is going to make the jump from 100ma to 3 amps or be able to handle the voltage swing from -80 vdc to +80 vdc????? These jerks on ebay who sell 40 year old transistors should not be trusted. You are throwing your money out the window. Sure, we have die hard's who want to keep their amps as they came from the factory, and on the other hand, we have dudes who are too broke to buy new fresh replacements but the results are the same in the end. The 40 year old transistors are junk..... Plain and simple. They were not made to last forever. They have a limited life (as do all electronic components) and you don't know what their history is so it's a dumb crap shoot trusting your amp to NOT catch on fire and burn your house down. If you don't have the money to do it, make do with a cheap Yamaha Receiver and place a tip jar on a speaker and do what we used to do in the old days and SAVE FOR A RAINY DAY!!!! Remember when we used to squirrel our quarters away from mowing lawns in the summer to buy that new Transistor Radio from the Five and Dime??? Or a new Huffy Bicycle with the banana seat???? If you haven't learned from the Pages and Sages of this web site, that scrimping and rigoneering shit to get it to work is a waste of time and worse yet, A waste of good money. Get a piggy bank and save for those shiny new output transistors or White Oak Audio Design Circuit Boards. Get a piggy Bank, and save for the Huffy Bike. Get a Piggy Bank and save for your yearly trip to the hookers because even old hookers are a "crap shoot" (and I do mean CRAP SHOOT). Not that there is such a thing as a new hooker but you get my point. I have boxes full of old transistors and yeah, I could sell them to goof balls on the internet but I don't. I do offer from time to time, the old circuit boards out of 700's but I advertise them as needing restoration..... i.e. NEW PARTS
Don't take it in the shorts (no pun intended) of buying or using 40 year old electronics parts......... You risk life and limb buy doing so..... Burning down your house is a bad thing to do when you are passed out in your recliner. When you hear "Flame Linear" from anybody,it shows they don't know shit..... Those output transistor blew up when they were put through stresses of chuckle heads who thought a Home Stereo was a good idea for use as a tool for rock bands wanting to entertain 20,000 people and make their ears bleed (cool Huh???) So, you just bought a pile of 40 year old transistors for use in your new partial WOPL project, they gave up the ghost and smoked your new $200 circuit board..... All I got's to say is..... ah, never mind.... But bonehead does come to mind..... The Control Board is not what I would upgrade first if I was trying to cheese out..... It would be the back planes and output transistors.... That's where the "Rubber Meets The Road" and where all that current is flowing, which is the main cause of electronics melt-downs... When is the last time you saw a crystal radio blow up??? You know why??? There isnt shit for current flow and no output transistors using enough current to weld the frame on an old car. Or better yet...... GET A PIGGY BANK so you can do it all at once when you get enough money...... You didn't go to the five and dime and buy a pedal to build a bicycle, you saved till you had enough to buy the whole fucking bike...... I give a full lifetime warranty on my amps because I trust my work, and the new components I use to build them. I don't do partial upgrades for my customers because the old junk mixed with the new junk is a recipe for disaster...... I'm a big dummy and even I know that the old shit I just put into a partially rebuilt amp IS GOING TO BLOW THE HELL UP sooner or later and would be a losing proposition. Let alone giving myself a bad name because every amp I build let a cloud of smoke out the top big enough to choke a horse... That half upgraded amp IS going to fail.... Just do some reading. As a proud builder of a hundred WOPL amps, I know what I am taking about... or....... Maybe not.
Yep, I know that everybody here may not have the money to build a Fresh amp but I also know that the same people DO have enough to buy a Piggy Bank...
This one is only 12 bucks on ebay
