HR-895 Dim Display

Has anyone ever seen an HR-895 where some of the display characters seem as though they only about half as bright as others? I'm just wondering if there's a fix for this.

it's good to be back..

Re: Power conditioners.....

the world of powerline surge suppression is basically centered around four approaches: 1) metal oxide varistor (mov); by far the most popular and also very effective 3) silicon avalanche diode; also known at transient voltaqge suppresor (tvs) or transorb 3) gas diode tube (gdt); has been used for ma...

Re: Power conditioners.....

I always thought of isolation transformers like trash compactors. They turn 120 pounds (read: volts) of garbage into 120 pounds of garbage. exactly what i was trying to say - isolation transformers do nothing to clean the mains. my previous post involving 'numbers' also had nothing to do with clean...

Re: Power conditioners.....

Rainman i disagree isolation transformers do virtually nothing to protect against power line spikes. all an isolation transformer is a two winding transformer; a 120 volt primary and a 120 volt secondary. this type of transfomer simply floats the ground so that ground loops and/or probability of ele...

Re: Cinema Grand versus Theater Grand

yes - that's the cinema grand amplifier i'm referring to. however, the theater grand i'm referring to is also an amplifier as shown in the pic (not the processor though). are the guts of the theater grand amplifier the same as the cinema grand amplifier?

Cinema Grand versus Theater Grand

I lust for one or the other....Does anyone know what the difference is between the Theater Grand versus the Cinema Grand series of 5/7 channel amplifiers? I realize that the Cinema Grand has a nice energy meter - but I'm not familiar with any other differences. My current HT Receiver has built in am...

Re: Need some Caps!

Electrically non-polar electrolytics are two conventional electrolytic capacitors in series with the cathodes connected together. In actual construction, they are composed of two pre-anodized aluminum foils wound together. Unlike a conventional electrolytic capacitor, the applied voltage does not se...

Re: Got any vaseline?

stated differently - creates more of an ac short = reduction in inductance (millihenries or dumbohenries it doesn't matter). you might be shocked to see the huge amount that the inductance is reduced with that single shorted turn!! i'm not going to solve the problem for you this time, but i'll check...

Re: Got any vaseline?

one last time (i promise). you cannot take a reading. the difference cannot be measured. you need to check the capacitors.

Re: Got any vaseline?

restated - you should be far more interested in the capacitors than the inductors (coils). capaciors are high failure components. inductors are not. with the exception of being open circuit - inductor health cannot be judged with an ohmeter.

Re: Got any vaseline?

it's important to remember that all you need is a single shorted turn, and the inductor turns into an ac short. this cannot be measured with an ohmeter which is only passing a dc current to make its measurement. since inductors normally have many many turns, a single shorted turn causes dc resistanc...

Re: Need some Caps!

="]RichP714While this can be done in a pinch, it's not recommended. The forming process of a polarized electrolytic by it's nature creates a positive and negative plate...hook it up backwards and it erupts violently. Hook them up back to back, as suggested, and it will work, but the small leakage c...
