I've been out of the audio loop since my Rotel took a dive ... along with work prospects. lol One day ... I will have it seen to. But I seriously .... miss my music these days. I was using the Kenwood KA 2000 for a while .... but it was missing something on the B&W 330s. I decided to hook up...

Lying in sun on the slab and streaming from PC to phone with earbuds.

Not sure of the year but I had already bought my DM 11s from Norman Foglar in Cape Town. Later I went in to buy a Technics amp. He took my arm and dragged me to his whiteboard. It was filled with newspaper clippings and reviews of the NAD 3020. I came out with the 3020. Is a gorgeous sounding...

I had slowed down on my music time because the big Rotel is still MIA. So ..... I spent a few minutes twiddling the knobs and balance on the teeny Kenwood 12w amp after lunch. Not sure exactly what happened but it sounds so magic today. I keep thinking of what we missed as a family back in the...

I've been told not to keep things bottled up. So I've just opened a bottle of red from a good friend.

I had a slowly dying Samsung Galaxy S4 phone. Less and less apps were working as time went by. The last OEM ROM was Android. 4.4 (IIRC) The Infrared remote worked with Anymote from the Playstore. I bought the full version. I rooted it years ago and installed CM 11 & later CM 12 ... Android 5.5...

Still no real difference. R641 is at 2mv (bad one) R642 is at 3mv. (good one) Turning the left VR601 does not seem to have any effect ?? Noticed it seems to be the lower frequencies which are distorted. Mids and upper seem to be OK ? What is the possibility that the bias is faulty ? And ...

Just switched on now ... not warmed up yet. But did a "practice" run. R641 is 2,2mv (The bad left channel) R642 is 2,6mv (The good right channel) Will repeat in a few minutes. This is so cool .... I'm learning "stuff" while referring to the schematic. "VR" ...is..... variable resistor ? ( the...

Hope it's ok to put the MM probes in there ? So .... I put the probes across the resistor and then adjust the blue pots until I get 5mv ? Pics of R641 and R642. (I do hereby bequeath all my belongings to my girlfriend. lol)

The hum went away after I cleaned the insides and screwed the covers back on yesterday.

Thanks Handsome. Then I think I'm out of my depth here in adjusting anything. I'll have to take it in when I get some funds again.

OK, now I'm a little lost here. My service manual is on the PC and no Eskom yet. I posted a page yesterday which mentioned the bias should be "5" millivolts. I got readings at the speaker terminals of close to that. Measured right after switch on. Today, after a 20 minute warm up with music...

I'll give it a bash when Eskom is up again ... that will be after 16h00. Can I use a normal narrow blade screw driver or should it be plastic or similar. Keep in mind, I've never worked on live appliance before. lol What would cause it to go out like that ?

OK ... this doesn't look good to me. Playing LM softly for 20 minutes. Left channel speaker voltage 0,259. (scale set to 2v) (The distorted channel) Right channel speaker voltage 0,025 (scale set to 2v) OVHD + LM Radio as source on AUX 1 Two different MM used, similar readings. All looks...

Thank you so much for helping Eric. Memory is a fantastic ability. While still school children, I remember my dad telling us how to use the Garrard TT (in it's homemade "box") and how we had to turn the Kenwood's volume down when switching it in. Now at 67 I automatically went through his...
