Rayovac doesn't disclose the detail of its charging scheme for their chargers. But PS1 and PS3 must NOT be doing simple "capacity sensing" scheme. When I charge multiple cells of same type/capacity, each cell completes charging in different time. They most likely sense the delta-curve to...

The current version of Rayovac PS1 and PS3 chargers do have trickle-charge after the main charging cycle is complete. I agree that PS1 may take long to charge high capacity AA cells from empty. But PS3 is much faster and takes quite reasonable time to fully charge any size/capacity of cells. BTW...

Rayovac PS1 and PS3 chargers are affordable ($10 and $20, respectively) and widely available. They have separate charging circuits (and LEDs) for each cell and stop automatically when fully charged. See the following manufacturer link. http://www.rayovac.com/products/recharge/chargers.shtml...

See a third picture at http://headwize2.powerpill.org/ubb/s...num=2&tid=2757 It shows a plug-in socket for external power supply already on the PC II board

It also happended to my KSC-35 recently - rattling static on loud passage. I opened the foam cushion and blew the driver both inside and outside. It seems to cure the problem. Blow the driver and then check if the problem is gone. Hope it also works for your PortaPro which uses the same kind of...

Well, solid-state manufacturing isn't perfect as any other manufacturing. There might be some chemical residue in the solid-state, some mobile ions hanging around, some moisture near metal-ss contact junctions, some atomic scale obstacle in the current paths, etc. When power is applied to the SS...

Rayovac 3-In-1 NiMH/NiCd/Alkaline charger is another quality charger that costs only about $10 and is widely available. It has four independent charging circuits (which is unusual in this class) and each circuit automatically stops when the cell is fully charged. I have great results with...

Beagle, the polarity doesn't matter as the adapter output is AC (alternating current). So, don't worry; it won't fry your X-Can .

Hi crymsonsunset, could you try the CDP's headphone jack to feed Airhead instead of the line-out? I am suspecting that the under-used line-out connection might be faulty. My Panasonic CDP had poor connection on line-out that caused static and horrible sound when connected to a headphone amp...

Jan told me we don't pay import duty for items under US$250, and I didn't pay the duty tax for my Porta Corda order. Well, this is for USA, and I am not sure for other countries.

I have Rayovac 9V NiMH battery which measures 9.6V when powering my amp. So Plainviews is not the only one giving higher than 9V. The Rayovac is also least expensive in places like Wal-Mart at $6.97. The Plainviews may have higher capacity though (and more $$). Mine charges fine on old NiCd...

I had the same experience as BenG: noise peaked at 11 o'clock in my case. Also when I slightly knock my finger on headphone jack, volume knob, or power jack in the back, I hear some funny (filament vibration?) noise on headphone which eventually fades away. Out of curiosity, I opened my...

David, I would first check if the 9V battery is still good. When the battery is dying, you may experience some strange things including annoying static noise. BTW, the CD player headphone output can't damage your Porta Corda by hooking it up into Corda's input.

anishbenji, 1-3A powersupply is way too excessive for porta corda which only consumes average 10mA on 9V battery according to Jan. Even if the corda consumes somewhat more for higher supply voltage, that's still excessive; one tenth of it should be more than enough in my opinion.

High quality (headphone) sound leads to high quality sleep fast. Seriously I tends to fall asleep more with rich satisfying headphone sounds late night.

The ksc35's clip is very strong and it should last years if not tens of years. Mine is more than two years and has replacement pads on it. Actually I tried to bend the plastic clip slightly (with heat) but no avail; they are too strong to change.

In a not so ideal setup at Goodguys, the Model One sounds slightly better to me than the Two. Model Two's FM reception was somewhat susceptible to my touch on knobs, perhaps it's RF front is very sensitive. I like Model Two's flexibility though.

RCA -> phone jack may not drive your headphones properly as phones have low impedance, several hundred Ohms or less, whereas the RCA is intended for high impedance load, Kilo Ohm range. You need a headphone amplifier. BTW, I often use my camcoder as a headphone amplifier by setting it in...

Regarding Russ' volume level question on headphone jacks, I think Scott answered it right. When the amp has high internal impedance (Ri), the current (I) through the inserted headphone will remain about the same for phones with different impedance (Rl). Note: I = V / (Ri + Rl). The 606's jack...

Gluegun, I am very happy with Panasonic RQ-SW88V and Koss ksc-35 on it. It is all metal construction except a few places; very ruggid and current model, $79.95 MSRP. RQ-SW99V and RQ-SW99VK would be similar; they come with funny looking headphones that may not appeal to your daddy. You can find...

The replacement ear pads from RadioShack help fitting the KSC-35 phones on my ears. They come four in a pack. Great sound.

I was also curious for the "VA" rating when I bought my AC adapter. I think that's the maximum power rating that the transformer can supply on its output. (In your case, it happens to be 12 VAC * 4.5A = 54 VA.) According to electrical theory, the source (transformer) and the output load consume...
