Crate Vintage club 212 60 watt Tube amplifier sound is off (not enough bass sound & midrange sounds louder despite its dial being turned low). Vaccuum tubes may need replacing, but I'm not sure how to tell.I have never replaced the tubes and the amp is 5yrs old, but I play it for an hour a day 1-3 days a week on average. Also what tubes would be good for a solid modern tone in this amp?

    I actually got this fixed. One tube was starting to fail, so my guitar tech replaced it. I also resoldered a connection in my footswitch, which was adding to the channel switching problem. The amp now sounds fine.

I agree with what Dan has said he's sounds outs faze brother... or some type of simple short... but i would NT recommend running the amp in this condition.. you could possibly ruin the OP trans. on this with a simple ohm miss match or run the added risk of shock or for rare death.. safety first.. sounds like an easy fix .. but remember plate voltage can and will get you .... oh yea im running electro harm' tubes and seems to help bring out that big vintage sound punchy cleans and well rounded dirty till holding tight bass ' with good spoungy mids..and ive tried lots of diff tubes/combos of them.. straite up Electro HarmX imho'was and is best for tone at live volume levels? hope this helps some one keith_plants@sbcglobal.net ~V

I just bought the Vintage Club 60 and am loving it. $300..Pretty good deal huh! Plenty of bass...Have you tried the low boost and mid boost switches? they completely change the way the amp sounds. Also the stock speakers are **** so I'm dopping some Celestion Vintage 30s. Also is anyone getting some tube jingle with the VC60? I'll probably have to take it to someone...

Have you moved any of the wires recently? What you are describing is how it would sound if the speakers were connected out of phase.

How many watts onkyo p3300 amp & pre-amp home stereo audio


Sorry I don't know the answer to your question because I don't know the specification of your amplifier but like a car engine that might have a capability of, say, 200 horsepower, in use and for practical purposes that figure is completely immaterial because most of those horses would never be used by a responsible driver. It requires only about 20 horsepower for an average car to maintain 50mph so it hardly matters what the potential power output is as long as it is capable of doing the work assigned to it.

The average person listening to a hi-fi in an average room requires an average power output of around half a watt. It is immaterial if the amplifier is capable of 50, 150 or 500 watts because for comfortable distortion-free listening most of that potential power will never be used.
With hi-fi the problems start with the speaker systems. It is a mistake to use a high power speaker in a domestic environment regardless of the potential amplifier power output. The amp will only produce the power it is capable of if it is driven hard (the volume turned up) and because doing that is anti-social, wasteful and harmful to health and comfort that should not happen but high power speakers tend not to reproduce sound efficiently at low power and so more power must be provided than would otherwise be needed with good low power speakers.
Fashions have changed and it is now difficult to find good hi-fi speakers for the domestic environment that reproduce sound efficiently at low power levels and speakers with a 10 watt rating, the ideal type for small to moderately-sized accommodation, are almost impossible to find these days but it is still possible to find good drive units rated at between 20 and 50 watts that perform fairly efficiently at social volume levels.

I have the following setup: AV Receiver: Pioneer


Very common problem with today's receivers. Receivers made today don't have a true preamp section in the amplifier and do not amplify the sound to the extent of an older receiver. I have large 15" front speakers on my system, and have stuck with my 15 year old receiver just because I know that a new receiver will not have the power to drive them well. Many of the newer receivers need to be turned up to 50-60% before you can even hear anything from the speakers.

My sony STR-DE475 has no bass. The bass just went out after running it for 6 hours.


Either the subwoofer speaker or its amplifier failed - they couldn't handle the extended use. Simple test to find out which: put the volume really low, connect another subwoofer (or a large normal speaker) to the bass output on the receiver and play some music. If you get sound then the original subwoofer is faulty, just get a new one. If you don't get sound then the amplifier for the subwoofer channel has failed. You could replace it yourself if you have enough electronics repair experience, otherwise it will be cheaper to just get another good sh low end receiver from a site like Ebay.

CRATE PA-B6350 no output


The 2 speaker jacks are wired in parallel. If your subs are 4 ohm rated the amp is seeing a 2 ohm load and may be trying to protect itself - hence the red light. I would suggest you unplug 1 of the subs and see if the problem goes away. You may have a problem with one of your subs. This amp is probably not the best choice for such demanding work as it is not fan cooled. Good luck.

I have a crate BX 160 that shuts down at the point where it starts limiting and then after a about 30 seconds. it starts back up. I would like to get a schematic on this particular piece of equipment...


I just saw your post. I happen to have a Crate BX-160 and was able to call Crate in St. Louis and talked with a tech there at the plant and he actually sent me full schematics for free.

Your problem, based on my electrical background and fixing audio equipment for 10 years, seems to be related to the built-in limiter in the power transformer. In other words, you might just need a new power transformer and it is a piece of cake to install (all push-on connections).

The schematic will show you the many test points for voltage checks, but unless you know what you are looking for, its just information overload. It is a rather simple amplifier and built resonably well. I have been using mine since 2003 and have fixed it a few times (age related problems like loose connections). There just is not much to go wrong on them except for the fact the amp is subjected to extream vibration. THis causes physical connections to fail resulting in vexing issues that are hard to solve. This is not unique to this amp (all bass amps).

I would bet anything your problem is the power supply shut-down circuitry is malfunctioning. In my expereience with amps, unless the amp is drawing current (failing power circuitry) and making strange sounds, the failure is usually not related to the power section failing (like power transformers going out). Likely, the built in limiter is the problem.

I hope this helps!

I have a crate Bass amp that is generating a distorted signal from the imput instrument and it will not clear up :what may be causing this condition on this unit?? Cc:Perplexed!!


Without hearing the distortion, it will be difficult to state with any confidence where in the amp the problem exists. That being said, the most common problem is with the preamp section. Many of these use 4558 chips as the pre-amp section. If hte chip is blown, the sound may still be heard, but it will be distorted. This is easily seen on a scope. The chips can be purchsed in bulk for les than $1, so the parts cost for the repair should be low.

Bad sound when running signals through


I would guess that the switching chip is faulty inside the receiver. Since the CD works OK, the amplifier section and pre-amp section are good. What you are hearing with the others is crosstalk. This chip shouldn't be more than about $10-$15. Add in the local labor rate for the total repair cost. I think that the chip for your model is a TC9163.
