Hello, new to the forum long time Fender user. I have a HRD I just picked up and it has died already. First off it's used but looks like it is brand new(no idea of manu. date/serial b-223136). So, I turn it on for the first time after buying it a couple days ago(it worked fine when I purchased). It sounded fine for about 3 minutes. I started out low volume. Turned it up a little bit and it cut out for about a second or two then came back on. Well about 20 seconds later it just stopped making any sound. The power is still on, the tubes are still glowing, the fuse has NOT popped. Any ideas on possible problems? Any help is appreciated.

Thanks

Not sure, I would check speaker connection first, it may be loose from vibration. I hope its something that simple. good luck. :)

Start with the speaker and go to the tubes, check for a good connection on the power tubes first.

then go to the pre amp tube at the far right (with you facing the back), check to see if its seated properly.

if all those things check out, its time for a tech or for you to find some tubes to swap out and see if you have a bad tube.

Still no sound at all. One question, should you see any blue in the tube at all? I mean it's glowing red on both ends of the tubes but there is a line of blue running from end to end. Call me a tube newb.

Blue glow is alright, here's some quick info from the interweb explaining:
BLUE GLOWS

Blue Glows are not tube detriments per se. They are, however, suspects in the eyes of many receiving tube users for lack of a full understanding of their origins. There are several types of Blue Glow which can be described as follows:

FLUORESCENCE-this type of glow is usually violet in color and most noticeable around the inside surface of the glass bulb. It is most pronounced on power tubes and is the product of electron bombardment of the glass taking place within the tube. It generally has no adverse affect upon receiver performance, and in fact, tubes displaying this phenomenon are particularily good with respect to gas content.

MERCURY VAPOR HAZE-is a blue-violet glow associated with those tube types which rely upon mercury vapor for proper operation. In such cases, the blue glow should be evident indicating proper operation.

GAS-produces a blue haze, generally confined to the vicinity of the mount structure. The proper function of gas types such as thyratrons, voltage regulator and voltage reference tubes, requires the presence of this glow as an indication of proper tube operation. Some voltage regulators use neon instead of argon and as a result exhibit a pink-orange glow. It is, however, a distinct detriment in vacuum receiving types, where the presence of gas in large amounts can cause malfunction of the equipment.

Flashing blue is bad a steady blue glow is o.k.

I was typing and talking at the same time.

My clients think I'm paying close attention to there life stories LOL !!!

If the speaker is good, I'd check the power tubes. If they are glowing real red they could be red plating and possibly cooked. Your bias may be way too high. And yes, a blue glow is okay.

I always warn about buying used HRD amps without any warranty being transferred. I'm sorry to hear about your problems.

I too had problems with my first HRD. Was getting some serious popping when playing at higher volumes (4 onwards). Had the tubes changed (as it had been in the store for a while) but didn't fix it. Got it swapped for a new one.

The new one I got was biased at 80mA rather than 60mA out of the shop and the reverb spring broke after 2 car rides. After rebiasing myself and installing a new reverb unit, it's been good as gold for 6 months.

After reading all the bad things about them, I really should have traded up to a Deville or DRRI. Trouble is I'm hooked on the sound of the HRD with the Jensen Alcino P12N.... love that thick warm tone.

I hope you can ride it out on the HDR, cause they really are workhorses when you get one working.

The DeVille is prone to the same problems as the HRDlx. It's the design and construction with cheap components that make them landfill pretty quickly.

The reissues are really reliable. If I were upgrading, I go with a DRRI. It's a great value for the money. I'd take 22 watts of great classic Fender tone over the icepick in the forehead tone and reliability issues of the HRD series. If you compare them side by side you'll understand what I mean. I bought a HRDlx because I wanted a Fender with something different than the usual, because Fender's pretty much all I've ever has since the 60's and all I got were problems. My HRDlx sounded okay until I cranked it a bit, then the tonal issues cropped up. The brittle highs, and farty low end. So I sold it.

Well I am just going to take it in and have some of the mods done while its there. Good thing is I didn't pay a lot for the amp. Low enough to go ahead and have it serviced. I'm also thinking of having it totally changed to a tweed pro. What stinks is I had a Devill 2x12 usa model and never had any issues with it. I only sold that because I needed to. Thanks for all the input. Any good company's for kits for the mods. So far I've seen a kit by a company called Fromel.

Be careful modding it. If you think you have reliability issues now you'll open up a whole new can of worms if you mod it. The traces are very fragile as is the PCB.

The biggest issue with the HRDlx is the two cement resistors mounted right on the board. These things really heat up and the heat damages the board. Many time you can get the amp running again by replacing these resistors. When you do this, leave the leads long and let the resistors stand off the board as far as possible Another thing to check is the solder connections on the tube sockets. re-flow and reheat the joints.

This all assumes that you know how to safely work on amps without electrocuting yourself.

So I got the amp back. I was told the original problem was an "open circuit in the output". Anybody else have that issue? Is it a problem that will come up again?
