transformer

Question, please... I know the consensus on here is it is ok to use a step down transformer (for Japanese amps 100 volts to be used in the USA 120 volts). But what about the frequency indifferences? I read where those can not be converted in a transformer. I read where a transformer can support...

Hello, this is my first post here. I was wondering if anyone could shed some light on the differences between using dedicated voltage amplifier and step up transformer with speaker amplifier to drive electrostatic headphones. I've tried electrostatic headphones recently and I am thinking...

Hi. I have a pair of Yamaha MSP5 that I bought in Argentina (Made in china) and they are 230V 60W 50Hz. I brought them home (Costa Rica) and the voltage here is 110V, and I realized this problem when I tried to make my first listen. Can someone explain to me what should I buy? I know I can...

Hi everybody, I need help making an XLR input on a regular single end amplifier. Since regular cable adapters wouldn't work, I decided using a transformer and already got the general purpose Lundahl 1588. I saw that they use them in some high end amplifiers. The reason I need XLR input is for...

One of my next projects is a valve amplifier. I built many solid state amplifiers and I'm very happy with these. I always considered valve amplifiers as being vastly inferior to solid state one but nevertheless I would like to build one to measure it and to listen to it. From all the available...

Mains related hum and noise in power amplifiers We have had some discussion in another thread https://www.audiosciencereview.com/forum/index.php?threads/class-a-vs-ab-do-they-really-sound-different.18415/post-910720 about the reason of higher residual mains related components hum in the...

I'm trying to put together a linear power supply for a TPA3255 board. I ordered a transformer from a company who shall remain nameless. It's 500VA and 34V transformer. They have two at these specs. One simply has 2x outputs at 7.4A (according to their specs). The other one has 2x 34V at 5.8A, 2x...
