RTP-15 SMPS For Tube Amplifier
Description
SMPS has several benefit over iron transformer in tube amplifier. First of all it has very low internal impedance (about 6 Ohm vs more than 50 Ohm of transformer). This feature will improve the dynamic of tube amp significantly. Second, the effeciency is much higher than transformer. Third, SMPS is much lighter than transformer.
Features
RTP-15 is designed for integrated amplifiers has output power of 15Wx2 (PP) or 8Wx2(SE).
- Input voltage: 100V-240V
- Output HV: 280V 300mA
- Output LV: 6.3V*1A, 6.3V*2A, 6.3V*2A, regulated seperately
- Switching frequency: >80KHz
- Dimension: 158mm x 100mm x 38mm
- Weight: 480g
Recommended Applications
6V6 SE, EL34 SE, 6P3P SE, EL84 PP...

Hi Globug
It's isolated from the power line. There's a screw connected to the enclosure. It can be connected to the GND when working, but for some application the enclosures don't need to be connected to GND.

It's up to you, I just wanted to give you the heads up that you need the ground with more then 42v and/or over 100VA.
These guys are tough cookies.

SiliconRay,
Very nice! An addition to your webstore?
Is the switching frequency of the 6.3V supply also over 80khz? What sort of regulation is used?

Hi greenvalve
They are under aging process, not listed for sale yet.
This is a CE certified product, can be batch sold worldwide. price is not determined, but won't be higher than a transformer system. The sample was sent to a big Japanese buyer a few days before, I'm not sure wether there'll be some left for the forum members. But won't be too long for the 2nd run.

@siliconray
is it adjustible by any chance to say +- 68v 2.5A to be used with digital amps ?
if possible also could you outline difference compared to

thx

Please read the spec....
The one you have quoted is 24V output.
The one in the thread has HT plus HEATER outputs.
Some user reviews would be very helpful... How does it sound compare to traditional PT? Many old SMPS had bad rep for being noisy (EMI), etc. Is this one quiet?
This module is underspecified on the web page. Is there a comprehensive spec sheet?
What's the total power for this module? Can I use all the outputs at full power? If I add up all the outputs I get 115W.
How much ripple and noise on the outputs?
What type of control is used? is it variable frequency?
What is the actual efficiency?
What's the maximum capacative load? Can it drive an inductive load?
Thanks,
Michael

This is a Class 1 PSU per UL1012...if it's not UL approved and you're selling it in the States...eek. Is it double-isolated (if there's no ground) as mandated by EU law?
I'm on the verge of going 'production' on a compact tube combo amplifier for guitar, and your #1493 RTP-15 looks almost perfect.
This is a 12W unit with a remarkably powerful 8" speaker and 2XEL34 turning out about 40W max in a cathode-biased Push-pull topology.
Input will be 115/120V 60Hz.
Preamp tubes in this model consist of a single 12DW7 and one EF86.
While the 280V is a bit lower than what I would like, I could deal with that, and the 300mA seems adequate, so my first question regards how that translates to your stated output power of "15Wx2 (PP)"? My prototype uses an Edcor transformer that's only rated at 180mA, albeit at higher voltages, and that's adequate.
So, questions are 1. Will this work for my application as is? (Have yet to do all the relevant math.)
2. Any possibility of getting something with a bit higher output voltage? I know there are lots of units out there that deliver 360V, but that filament output on yours is a real bonus!
Thanks.

Hi siliconray,
on your homepage the RTP-15 smps is marked as "out of stock". When will it be available again?

Anybody know if there are other sources of similar units? Looked like exactly what I needed.
