After one month I sent my amp to be beefed up here is a quote from the tech-

"The ribbon cables had begun to break, as you must have noticed because one had already been replaced by red wire, so I replaced them all with more flexible and reliable wire. Finally, I checked the tube bias to make sure your amp is running and sounding the best it can.

Normally, we charge $120 for the labor to install a Supreme Kit in these amps. Our hourly labor rate is $60 and an install usually takes about two hours so that works out. Unfortunately I had to spend five hours to do all the repairs on your amp, but I'm only going to charge you the equivilant of three hours: $180.

I think this is fair and I hope you do too. I definitely don't want to charge you a huge amount because you happen to have an extra fragile circuit board.

Out of warranty, or are you doing this off the bat?

wander02,

Curious as to why you found all this necessary to be done.

My BDRI is two years old and I have not had a single problem with it. Granted, I don't gig, but there are others who do with that amp and they have not resorted to anything like this. The ribbon cables are a known problem, but they are only a problem if the amp is opened and the circuit board removed repeatedly. They will not break just sitting there untouched. What others have done, and I did, was run a bead of clear silicone along the ribbon cables where they bend around the circuit board. I also find nothing fragile in the BDRI circuit board. It is a significant improvement over the earlier Hot Rod boards. All component connections on the PCB are through plated meaning that both sides of the board and inside the component mounting hole are plated for soldering. The earlier Hot Rods were only plated on one side. Through plating makes for a much more robust solder joint.

An update with clarification-

"I only meant that these circuit boards are fragile to work on, specifically. They have traces on both sides of the board meaning that the holes are "plated-through" making it extra difficult to remove parts without damaging the solder pads. Other than trying to work on them, these boards are actually more sturdy as they hold the components more thoroughly. The way I repaired the damaged parts is quite strong and you shouldn't have any problems. I am confident in the integrity of my work and think it will stand up to any normal or slightly-more-than-normal moving around situations."

That is BS. I have found that through plating make is EASIER to remove a part. Easier because you don't have to remove the PCB from the amp to get at the solder pad like you had to with the earlier Hot Rod amps. That is where most of the damage occurs.

Still curious as to why all this work was necessary.

You are right , all tech know that. That's why you see lots of 45 years old amp , they are point to point ,no PCB

You won't see a BDRI work in 45 years , or any PCB amp.

Hey why don't we stock a lots of new BDRI for make a lots of money ......in 45 years ?

So you don't think this amp will be working in 45 years?

Looks like a PCB amp to me. :wink:

my bdri amp is 3 yrs old and i haven't had any of the problems that folks talk about on this site. i even had a guy accidently kick the crap out of it and knocked it over with it on. it didn't even break a tube. it just made a extra loud reverb thunder and kept on playing. i don't get it. i guess i must be blessed.

This one will work in 100 years... This is a high quality made PCB and amp.

My response was intended general .There is much more fragile PCB circuit they do not resist the years.

Or they will break too often and /or too expensive to repair because of a technician's time. This is not the case of point to point circuits

Now, now. Your original statement was "any PCB amp". :wink: :lol:

By the way, the amp pictured is a Soldano SLO. :shock: 8)

Right bluesky, your Soldano look very well built and with high quality parts , like some British amps I already see.

But IMO , 99 % of amp made are built with cheap PCBoard and other low cost components. That is why it is so easy to generalize .

This doesn't mean these low cost PCB amp are not a good buy and can't play well.

blackstrat71 : 3 years , it is so short

WTF?

The "tech" double-talk is hard to figure. "..fragile to work on...these boards are actually more sturdy..." :?

If the OP only had the new amp for one month, when did the ribbon cable get replaced with red wires before going to the tech? Is it a new amp made in 2012, one owner, or is it a used amp?

As bluesky636 pointed out, BS, the ribbon cables don't "begin to break" on their own. And through-hole plated is not fragile, quite the opposite.

And why take a one month old amp in to be "beefed up" in the first place? That also makes no sense.

Someone is FOS, .... and/or this is a used amp that has been worked on before. And where and when was this amp purchased?

I hate the smell of BS in the morning. :x

The OP has been asked at least twice why this work was necessary. Still no response.
