Another PA amp getting slaughtered!

[Hermansson Amplification]

Another Laney PA 100 on my working bench, this is the fifth Laney PA 100 I have had my soldering iron in.

Looking like usual, lots of mustard caps and big Partridge transformers

And as always I emptied it and made room for new circuits.

New circuits in place!

This amp has four independent channels, tube buffered effects loop, PPIMV and a lot of crunch

Here is a close mic'd clip, recorded with a Shure SM57 and a Sennheiser MD421:

Here is a clip that is recorded with my Iphone 4S:

Another killer. Great work!

Thanks guys!

Your amps are amazing! Easily some of my favorite on the forum.

 

[skoora]

See, just a couple of tweaks to the original and you're there

Nice work as always.

 

[tokyo tapes]

Nice Henric! Sounds great as ususal!!!

 

[Aidanspaghetti]

Outstanding Henric!

 

[IndyWS6]

Sounds great!

I love the range from edgy clean to rock & roll crunch with the volume knob at ~4:00 in the first video.

Nice work!

Very cool.

But now since you've got your circuitry, why don't you go with PCBs and your own designed metal chassis? Should safe a lot of work . . .

 

[rupe]

Another well done project...sounds great!

 

[midnightlaundry]

Sounds rippin! How much of that tone is in those old Mustard Caps?

 

[blackba]

Can you share roughly how much you charge to transform one of those amps?

score...

I have considered it, but I'm not sure I want to go PCB. I have planned to start up a company in the near future and begin to make the first "Hermansson Amps". But I haven't decide yet if I shall make a four channel point to point monster or go PCB like all the others do
It's very time consuming to build point to point but I kind of like to do it the old fashioned way Maybe I will do both, does todays guitarists only look at the price tag of an amp or do they care about the inside?

It totaly depends on how big project it is. Smaller project can take 2-4 days and the biggest projects can take over 4 weeks. Send me a PM if you want more details.

Thanks! Most of the tone is in the circuit design but old mustard capacitors doesn't make it sound worse, especially not if you listen with your eyes
It depends on who you ask, some will say that "it's all in the mustards" and some will say that any polyester/polypropylen capacitor will sound as good, and I don't know if any of them would hear any difference in a blind test They were used in old Marshall's, Vox's and Hiwatt's etc. that all sounded great so they are for sure really good sounding capacitors if you use them in a guitar amps but you need a good circuit and a good layout to make any high gain amp sound good.

Right on then. It sounds great.

That's a huge vintage Power transformer, what's the plate voltage on your power tubes?

The plate voltage in this beast is 608V!

I would buy Channel 3 of that amp all day long!!! That tone range was just sick! You hit every desired tone that I look for in that one channel. lol!

 

[midnightlaundry]

LOL. How many watts RMS do you think you're pushing?

I found the data sheet for those tubes.
