How can I buy one of these regulators for my tube amp?

How do I get in touch with you?
Sorry for being not familiar with things on this website. I was searching for a voltage regulator for my HH Scott tube amplifier and through a few links got here. The secondary side of the power supply transformer puts out 400 volts AC. Would your regulator board be able to put out a constant 400 volts AC? Again I am new to this forum site and I do not know how to get in contact with you.

Hi Mark, most people come through my website, see my sig line. Or send a PM through the forum if you want to keep your email address private; you can do that through the user command post, see top menu line: userCP
You probably want 400VDC rather than 400VAC from your regulated supply?
How much current do you need?

current limit
DC would mean I connect the input of the regulator to the output of the rectifier tube. Ok, I get that. Sorry, where was my brain? For the current the schematic shows 400V at 150mA out of the 5U4GA rectifier tube.

So 400VDC out of the rectifier, with ripple on it, means that the output of the regulator to your amp will need to be less. Does the schematic show what the voltage is on the amp? Generally shown as 'B+' or something like that.

B plus voltage
Hi, don’t hate me for being a little green for not knowing what B plus means. If at all possible, the amplifier in question is an HH Scott 99D audio amplifier. Is it possible that you can do a quick google search for the schematic to help me out?
Tnx!

Sad that we couldn't have done business
Hi Jan, I have supplied you with the schematic and answered all of your questions regarding your regulator circuit so I take your no response as a NO-GO.

I was waiting for it to come alive here, as requested.
I looked at your schematic, there are several different B+ voltages. For me, the most critical one is the one supplying the pre-stages, the 240V. I'd be happy to provide you with a T-reg regulator for that. But as you mentioned you are starting in diyaudio (at least that is what I understood), maybe you want to cut your teeth first on something less drastic? Are you comfortable to assemble a regulator, understanding its operation, testing it, fault-finding if you make a mistake?
Maybe a less drastic undertaking like replacing some suspect, old electrolytics to get the hang of it?

Hi Jan
Hi Jan I misunderstood the earlier no response. As far as electronics go I am pretty familiar with some but not all. I just did some work on 2 dead HH Scott 99D audio amplifiers about 2 weeks ago. I love the sound of tubes, especially the 300B tube. In the 2 amps that I just repaired, I replaced all the bumblebee caps. Just about every one was way out of tolerance on my capacitor tester. I also installed brand new custom built filter cans. I replaced all of the high wattage resistors. I installed thermistors going to the on/off switches. Just about every tube in both amps tested weak, all except the rectifier tubes. I installed all brand new tubes and diodes in place of the rectifier tube (one less tube to worry about!) I just got brand new tube sockets that this weekend I will be changing out all tube sockets in both amps. I will also be changing out both line cords with 3 wire line cords. By trade I am a senior RF Electronic Technician for 27 years. Do to the economy I currently am employed as a technician working on switch mode power supplies (the BIG switching supplies with crazy power) I am also a Ham radio operator with 40 years. I do have experience with electronics and troubleshooting and very proficient in soldering. I also just updated an old NRI model 70 tube tester with a diode and changed out 2 of the resistors in the diodes path due to the diodes greater efficiency. Also recalibrated the tube tester according to the correct procedure

Regulator
I came across your regulator device on EBay. There are two of them for sale. Question is, how old are they since I see on your Website that you have made revisions. I did some research on the internet and came across your Website then wound up here. I want to try an experiment where I keep the 400 volts out of the rectifier tube (well now they are two diodes because that’s what I replaced the rectifier tube with) regulated. All of my B+ voltages are done so by dropping resistors. Not concerned with that part of the circuit. I am concerned with the 400 volts FEEDING that circuit. I understand on regulators usually you need a higher voltage IN. I can use 400 volts into your regulator and come out with 375 volts which is the first B+ voltage. Then I need to derive at the other B+ voltages by changing the dropping resistors that are on the schematic with resistors that would produce the correct voltages for the other B+ voltages.

Lost a customer
Jan, I have given you plenty of time to respond to me. Keep your regulator thing. I don’t want it!
Have a great day!

Man, you're in a hurry! This is a hobby project/ Group Buy, and I generally respond within a day. I'm not generally looking at people building my stuff as 'customers'. Sorry to disappoint you.
As to the experience, I just wanted to make sure you knew what you would be getting into, as you obviously are. It is often hard to gauge people's experience from a post, and it is also very hard and extremely time consuming to remotely debug projects with people just starting out at diyaudio. I always do, but I also try to avoid such situations as they are hard both on me as well as on the diy-er.

I thought you supplied your product to customers
Sorry for mis-understanding things. And I haven’t a clue to what a group buy is? I saw a person on EBay selling basically the same thing that you designed. It’s a bit different though. They have a product where you can put in 100-500 volts and get a regulated voltage out of up to 400 volts which is adjustable with a potentiometer. It has a 40 volt drop. I guess that’s the drop through the circuit. I spoke actually to the owner of the company. They said they have sold thousands of these boards since I think 2003. Sorry to start things off a bit aggressive. I thought you made a product and sold it to customers. Again Ibhave no idea what this group buy thing is all about.
