Crickey my English is dreadful, sorry about that.
Ha! I'm on the other side of the pond, so who knows from English?
Have a great day, bedtime for me!
Crickey my English is dreadful, sorry about that.
In the new amps I am designing the above circuit is added to them all plus a few refinements.
I was going to use a transformer and a cap to set the transformer into resonant, but the 1500 V on the cap worried me as it would burn finger a bit.
The prototype rejects below 40Hz and above 100Hz, we used the same technique at Harmer and Simmons for battery charger 55VDC at 100,000Amps,
The then drove a series regulator using chop thyristors (3 phase) followed by 1000s of transistors to regulate the last few volts but we manged at full load to only have 5mV ripple.
A wicked beast to cut your teeth on when first starting out at a real job of work. I recommend it.
Although I never did any of it myself, I hugely admired our engineers who designed and built 500kW-2MW shortwave transmitters and 100kW UHF TV transmitters. Real engineering with potentially big bangs!I did a bit of that but it was boring no big bangs.
That's the one that is working 90% of the time for me. Great device.ATLHifi offers a version with a higher blocking threshold
Yes -- I am a little surprised. From their website:
High-performance glass passivated semiconductor. High-case dielectric strength of 1500VRMS. UL listed. Flame resistant IEC socket/connecter/chassis (Fireproof polymers UL94-V0).
I have used both the iFi and ATL (2V version) DC Blockers. Had the best result with the ATL. But not constantly, unfortunately. Eventually I decided to replace my amp by 2 Purifi monoblocks. I couldn't stand the hum anymore.
Hello, I have taken a look at the dc block that you have recommended, it would cost me about € 110 since I am from Spain. Do you think it could solve my problem?
Or better try the ifi dc blocker? Which do you think will be better?
I have read that these
devices degrade the sound and some say that the bass becomes flaccid, what do you think?
