No spares. I haven't done any tapping yet. I'll do a little and then quit.

Hi all, I haven't forgotten about you - just back from vacation. Maynard - why would I hear the ringing just on the phono input? Are the 12AX7's part of the phono stage? I'll do a bit more tapping over the next few days and report back. Many thanks for all the replies.

Hi all, I am currently running a Klipsch Quintet surround system, which works well in the room I have. A friend is about to gift me with a pair of SB-1 bookshelf speakers. It occurred to me that they might provide at least a bit fuller sound as the front surround speakers. Any thoughts?

Hello all, I have a restored Scott 299C tube amp. I have noticed that, when phono is selected as the input, there is a ringing sound when I tap on the transformers, or on the chassis. It's a low toned, short-lived ringing sound coming from the speakers. The unit is reacting to the vibrations when I tap it. This does not happen on any of the high-level inputs (tuner, extra). I'm concerned that, when the music gets a little loud, that vibrations can make their way in and influence the sound. Is this normal? Any insights appreciated.

Craig, excellent answer, that all makes sense and reconciles everything nicely. Thanks very much. BTW my model does in fact have a headphone jack on te front. Haven't tried it yet so i don't know if it cuts out the speakers or not. I am not a headphone guy so I don't even have a pair with the 1/4-inch plug.

On my Scott 299C amplifier, I have the following inputs on the input selector knob: Mic NAB Tape RIAA NAB Ortho Tuner Extra On the back, I have the following RCA connectors: MAG 1 High MAG 1 Lo MAG 2 High MAG 2 Lo Tuner Extra Recorder Playback Headphone I'm having some trouble reconciling the front of the unit with the back, in other words I can't match up the inputs on the rar with the positions on the selector switch. Tuner and Extra are easy. These are line level inputs with matching positions on the front selector knob. RIAA NAB Ortho is the phono input, either 1 or 2 as selected on the slide switch, and either lo or high level. The Playback input is heard when the tape monitor switch is IN, no matter the position of the input selector knob. This is a line level input. I hear the RECORDER input no matter what position the input selector knob is in, and this appears to be a line level input. Is this normal? What is the function of this input? I hear nothing on the NAB TAPE and MIC positions, and find no correlating RCA inputs on the back of the unit. What are these inputs for? Is the HEADPHONE an output on the back for headphones? These are two R and L RCA connections. There is also a 1/4-inch headphone jack on the front panel. Any assistance is much appreciated.

The turntable WAS on the right, amp on the left. I switched them, bring that transformer on the right side of the amp away from the turntable.

The amp is new. I had been running an HK solid sate amp until last Friday. The hum was always there, very low, but the buzz was much more apparent.

I consider the 12:30 to 1 o'clock position to be the maximum safe volume level. When i was a teen I would blow tweeters on a weekly basis, so I gained some experience with clipping and overload. It is the point at which the sound level is satisfying yet does not crowd the room or cause my ears to bleed or speaker components to smoke.

Followup: This evening I did some more fiddling, and found that one ground wire was enough, so that wasn't the solution. I was wondering if the ground point on the amp chassis made a difference - it did not. It could have been moving that power supply further away from the turntable, as Craig suggested. It could have been moving the floor lamp from behind the console (with an AC wire in close proximity to everything). Who knows. But now the buzz is gone. There is still hum, but it's well below and not much of a bother (although all other inputs are dead quiet).

Yes, no change.

Hi all, 1. Craig - by swapping the position of the amp and TT on the table, I was able to move that power transformer further away. But that didn't help (but I'm leaving it in that configuration anyway). 2. I swapped out cables between the TT and the amp, but that didn't help - until I connected the ground wire that is built into the second set of cables. Two ground points helped a lot. the buzz isn't entirely gone but it is low enough so that I can go to what i consider full volume (12-1 o'clock on the volume knob) without hearing the buzz. 3. I did wiggle the cartridge connections a little but that made no difference either way. The tonearm is aluminum on a VPI Classic 1. 4. I had tried reversing the plug on the amp, no change. I cannot do the same with the TT since it is 3-prong. I did move that plug to a different outlet - no change.

Thanks Craig. The cables are rock solid Luminous Audio cables that actually tighten onto the connector. I've gone between the two MAG LO inputs and get the same thing. Once the turntable is disconnected it's dead quiet, as it is on all the other inputs. I lifted the ground on the turntable but no joy. As far as location I have little choice in that matter. The turntable is indeed right next to the amp but there's nowhere else to go.

Hi all, I am getting a buzz on the phono input on my Scott 299C. It's low enough that I don't notice it until I turn the volume knob to the 12 o'clock position. The turntable is grounded to the amplifier chassis. When I disconnect the cables from the turntable the buzz goes away. The buzz does not appear on any other inputs. Any thoughts on how to make this go away? Many thanks,

I remember years ago, at the Music Box in Wellesley, Mass. (where I bought my Heresys), they ran a pair of Klipschorns with a Sony Walkman.

Hi Craig, So are you saying that in addition to the level control I set on the center channel output (via its dedicated level control on the front panel) that the output to the center channel will also rise and fall along with the main volume control?

Hello all, I am about to come into possession of a restored Scott 299C, which will drive my Heresy II speakers. I also have a Sub 12 subwoofer, which I will drive from the derived center channel output on the amp. The center channel output is independently adjustable on the 299C. For anyone out there with a similar set up, what's yoru routine for adjusting the output level to the subwoofer? Do you leave it at a certain level? Do you adjust it according to the regular volume level? Any insights appreciated.

Thanks a bunch, folks, good advice all. I have seen Craig's page but not Ken Leonard's. They both look like excellent resources. I am seeking a local authority first to have the unit checked out. Baring that I will look at those suggested. Tube Fanatic, I will send you a photo when the unit arrives nex week. I am located in Monmouth County, central New Jersey.

Here is the description from the ebay listing: "Up for Sale is A Vintage Scott 299C Tube Integrated Amplifier Amp. Unit has Been Cleaned and Tested. It is in Great Working Condition. All Controls Cleaned No scratchy Noise. All Tubes are GE Except 6U8A by Telefunkens. Clean Faceplate with Little Light Scratche as Show. Excellent Overall Condition." Photos show a pretty clean chassis, transformers look free of corrosion. the face plate is in excellent condition. It has the brown plastic knobs that show some corrosion on the ends. There was not a photo of the underside, and only a partial of the rear panel. There is no case (a friend has graciously offered to make one for me). Apparently there are two versions of the 299C, one with 28 watts per channel, another with 31. Not sure which one this is. Delivery is expected next week. I am looking forward to connecting my Heresy speakers.

Many thanks.

Hello all, I have just purchased a Scott 299C tube amp (to go with my heresy speakers). I have done some searching but need some help making the speaker connections. The wires that come out from the back of the amp connect to the terminal strip screw that corresponds to the impedance of the speakers, correct? To which screws do I connect the two wires on each speaker cable? High and 0? Any assistance appreciated. Joe

And so sorry, still cannot figure out how to get paragraph breaks. I'm using Safari on OS X.

Here's what I've found in terms of options: For subs: Sub-12 or KSW-12 For center: VC-25, RC-10 or RC-52 For rear surround: VS-14 or S-1 Keep in mind that this is for occasional movies and sports (we will have DirecTV and a Blu-Ray player) as well as iPod playback, FM and streaming audio. It does not have to be perfect as our ears are not that discerning (nor is our budget!) Many thanks.

Hi there, new to the forum but a Klipsch owner (Heresy II) since 1985. I am moving back to the states after an overseas assignment soon. I have a chance to build a home theater system from scratch. I would like to build around the Heresy's as front speakers, in order to use them for plain stereo music as well as 5.1 home theater. At the moment I have nothing but the Heresies in storage. I know that ideally everything should be matched, but I'm not sure my budget (or space) can handle more big speakers. How horrible would it be to use the Heresies as front main speakers and add in a sub, center, and rear surrounds from the current Klipsch line? I can spend some money but definitely not top end stuff. Any advice appreciated. P.S. who remembers the glue problem with Heresy speakers in the early 90's? The back of my speakers started to fall out a year or two out of warrantee. I called Klipsch just to ask how to fix them. They said, we don't want you to have those speakers, and they gave me a full replacement set. I was even more hooked on the company after that. Regards, Joe
