Absolutely perfect! I've been trying to understand how to use all or at least some of the features of the receiver and especially the remote.

Copy of genuine owners/operators manual, very useful
;
The manual was a perfect match and was exactly what I was looking for. I'm very satisfied with my purchase.

Thank you for having the manual I needed for an older model Aiwa stero I had found on Ebay --- I wanted the Aiwa because I had tapes and cd's but I did not have a manual as to how to operate the system... I found what I needed and it has enabled me to set the system up for my enjoyment.

I wished detailed information of the JBL S310 and here I found it! Very happy with the service from this site!

BV-60H/120H All-Tube Professional Series Guitar Amplifiers
A Word About Tubes:
Vacuum tubes can only last so long. Allowing your amp to cool down before moving it will help prolong the life of the tubes. Even so, after about a year (or sooner if you're on tour or jammin' more frequently than most) you may notice the output of your amp just isn't as "alive" as it used to be. If the sound from your amplifier starts to grow weak, lacks punch, fades up and down, loses highs and lows, gets "funny" (clanking sounds, etc.), it's very likely that the power tubes are worn out and need replacing. Since power tubes work together in an amplifier, it is important that they all be replaced at the same time with a matched set of tubes. If the amp starts to squeal, gets noisy, loses gain or starts to hum, the preamp tubes may be bad. Insist upon using only the highest quality, low-microphonic tubes! NOTE: Tube replacement should always be done by a qualified service technician, since adjustment of the internal biasing controls will be necessary after the new tubes are installed. Also, removal of the tubes may expose extremely hazardous voltage levels, which could cause injury or death.
To help prolong the life of your tube amplifier, and to keep it in top performing condition, please observe the following guidelines: � Always match the impedance of your speaker cabinet(s) to the amplifier�s impedance selector switch setting. � In cold weather, allow the amplifier to warm up to room temperature before turning it on (to prevent cracking the tubes). � Allow the amplifier a moment to cool down after playing it before you move it. � Protect the amplifier from exposure to dust and moisture. If liquid gets spilled into the amplifier, or if it gets dropped or excessively jarred, have it checked out at a service center before using it.
