Cary Audio SLA-70B amplifier
Does anyone have any idea the type and voltage/amperage requirements are for the power LED in the Cary SL-70B amp?  I have changed the resistors in question, and when I plug in the amp, the power fuse 3 AMP SLOW BLOW ---> BLOWS UP.  I'm thinkin...

Sr oldhvymec. With all due respect to someone that appears to know what the problem is and knows how to fix it ...... It does no good to give me a "hint". This is not a school atmosphere. I have a problem and I am going to the "forum" and am askin...

Hello imhififa. Your "link" takes me to a page that is not inexistence. Looks like it is from Italy? Don't know, but I could not get it open. Sorry my friend.

Hello decooney. Great info. Sorry to say that Sound & Music are a retailer of home sound equipment and have decent technicians that know how to INSTALL these equipments. They do very little repair.They're recommending someone else, but the tru...

Thanks for all your input and ideas. I'm sure they are all valuable. I have a few issues that may clarify some of my uncertainties. 1- I am 75 years "young" and cannot LIFT a 50 lb amplifier by myself; much less flip it over.  2- Although I am a r...

Based on the pictorial I can see the connections, but I cannot determine the CORECT VALUES. The small (blow-up) resistor, is it actually 100K 5W ??  And the 2 that are parallel: are they RED/VIOLET/YELLOW  ??  I can't tell.Do you know what are the...

Hey Oldhvymec..  I can see the pictorial,  finally!BTW: Those pictorials also show the bias potentiometer  OUTSIDE of the chassic. My amp is so old that the bias is inside. I think that is a fabulous idea to be able to modify my old amp.  The pict...

How you doing oldtimer, I mean oldhvymec. That's just the problem; I can't do a schematic; I cannot even send a photo because there is no place to upload a photo. And why I can't do a schematic? Because I don't know what goes connected to what.  W...

Bias adjustment for the CARY SLI-80 Integrated Amp
Great advise. Sounds simple enough. I do appreciate your wise comments about putting one hand in a pocket and discharging all caps. I will follow suit and give you an update after this weekend.Be well and stay well during these difficult times.Reg... 
Bias adjustment for the CARY SLI-80 Integrated Amp
Hello oldhvymec:   I reversed all the tubes; that is the left side tubes went into the right side, and viceversa. If it would be a tube, and only a tube, one would assume that the bias readings would be reversed, and that is not the case. After sw... 
Bias adjustment for the CARY SLI-80 Integrated Amp
To Jond: I don't live in the US, and the cost of shipping a 50 LB carton is very expensive. Second; I have sent it back to Cary around May 2020 and they claim they fixed it, and reset the bias,  and the bias issue was "all my fault". It worked for... 
Voltage Divider Linear Network
If I may try to explain what I'm trying to accomplish if it doable:  From the integrated amp, I connect RCA jacks into the L & R Sub-Woofer connections.  It seem to me like the Sub-Woofer connectors are connected to the volume control of the i... 
Voltage Divider Linear Network
Does anyone know what exactly is a "Voltage Divider Linear Network for Driving Active Sub-Woofers" ?? 
Bias adjustment
Hello oldhvymec. Yours has been probably the best and clearest explanation of all the "advices" I've had. I REALLY thank you for taking the time to explain the bias process.I've had a similar issue with Cary when my old SLA-70 Signature ran into t...
