Hi Paul,My question was of cause about my phonostage based on EAR834p and "End Of Live" modification with air capacitors and LCLC + 0A2 power supply.A couple weeks before I increase the second stage ECC83 cathode capacitor value to 43400uF (Kaisei no...

Hi N-set,Yes I added big cap bank to the second stage cathode. Yes it is possible to use filament power supply for fixed bias like Romy did.But I have a stereo EAR834p with a single filament PS. So, I was afraid that one PS for both channels can caus...

It's a MM/MC phono stage which at maximum gain provides 74dB. The price 329 GBP, higher if ordered with dedicated PSU, but that price includes "wallwart" AC transformer. You can take a look here: http://www.trichordresearch.com/dino.html They do...

Recently, I have become aware of a strange phenomenon after lifting the tonearm at the end of the run-out groooves. The record surface noise keeps going when the stylus is no longer in contact with the record. I am using a Garrard 301 with SME 3...

This was probably discused ten thousand times before, so I hope no one will shoot me for doing it yet again. I needed to get new tubes for my EAR834P, and decided to look at the options for a change, now that prices on good Tele's have skyrocketed so...

Folks,Before we discuss "high distortion" amplifiers, lets us ask what kind of SPL Romy's system produces.I don't know, so let me make some eduacated, conservative guesses.Let us assume his midrange and treble Systems are both 100db/W/m and he listen...

Hi Guy, [quote user="guy sergeant"]My experience with the 834p stemmed from having one at home for about a year soon after it was launched. I did try different types of ECC83 in it which did change it's balance slightly but not enough to make me like...

Hi Alex,I am sorry, what you claim can not be. No cap is going to separate bass instruments better.The brilliance of the 834p circuit is that the EQ also uses the miller capacitance of the tubes in a very brilliant way. The power supply caps are very...

[quote user="guy sergeant"] I don't doubt for a moment that there are plenty of people 'who know' who will wax lyrical about the benefits of open loop eq in feedback circuits. There are people 'who know' who will tell me that valve amplifiers cannot ...
