    Ca-1010 Transistor Replacements

    Oh, I totally forgot! After replacing all the 1212's and TR215 with a KSC1845 the lost channel came back! I also replaced all but the filter caps a little while later. Still use it as my daily driver and love it!

    Ca-1010 Transistor Replacements

    Found TR215 faulty which is a 2SC1775 and the VD1212 next to it open. All resistors, other transistors, and VD1212's are functional. I also noticed someone has worked on this before as some resistors and transistors have been replaced but were replaced with correct replacements. Time to order...

    Great! I got the board out and I'll post what I find.

    Ca-1010 Transistor Replacements

    Awesome, I'll take a look at that. Yes, seems to have 4 of them. From what I've read the replacement is two 1N4148 diodes in series?

    Will do. I'll also check the resistors then too.

    Ca-1010 Transistor Replacements

    Is there something else I should look at? I traced a signal around with an oscilloscope so I know the problem is in the tone control board. There are a few caps on there too.

    Ca-1010 Transistor Replacements

    Well for the 2SA872 it's $7 for two from a USA seller. It's not bad but just seems expensive for two transistors. However that may be a normal. I haven't taken the time yet to find which one is bad. Planning on doing the repairs this weekend, hopefully.

    Ca-1010 Transistor Replacements

    Hi, I have a ca1010 that loses a channel in the tone control board. I suspect it is a faulty transistor since I deoxed the controls and there is a intermittent electrical noise. I figure since I'll have to disassemble the amp to get to the board I might as well replace all of the transistors...

    Acoustat Speakers?

    Just saw two ads on Craigslist for a pair of Acoustat 1+1 speakers, but I believe one pair is actually model 3's? Here are the links and no affiliation. https://appleton.craigslist.org/ele/d/acoustat-speakers-1-1-model/6359415024.html...

    Pioneer Hpm-200 Speaker value

    Sorry, I've been busy and haven't been able to respond to anything. Unfortunately, no I did not get them. The seller was someone I knew and he got a better offer and I told him to go for it. Plus with heading off to college the money will be better spent elsewhere. I know these speakers are...

    Pioneer Hpm-200 Speaker value

    This will be the most I ever spent on stereo gear so I just want to be sure!

    Pioneer Hpm-200 Speaker value

    I have an opportunity to purchase a pair of pioneer hpm-200 speakers. Would $1700 be a fair price for a pair? They have all original drivers and everything works. In great shape too! Thanks!

    Yep, one was shorted.
