Page 1. Page 2. Page 3. Page 4. We do not want to use the impulse variant 6N6P-i later named 6N30P. We want the good old 6N6P only. ARG, which could use any tube they wanted, I mean. Description. The 6N6P (6Н6П) double triode is designed for low frequency power amplification. The 6N6P double triode are miniature devices enclosed in glass.

As can be seen, the line stage inverts phase, thus output transformer inputs can be swapped or speakers connection reversed. Select a valid country. Add to watch list Remove from watch list.
See all exclusiv-store has no other items for sale. Hum has been a serious problem with this line stage. Design implemented and it just works excellent. Spray used for stoves; makes a nice metallic surface, but rather fragile, thus Takes a lot of 6j6p Thanks to John for taking the time to respond to my WOT line stage!
Here is how I would do it: Components shaping up once more.
Resume making your offerif the page does not update immediately. Please let me make a few suggestions. Minimum monthly payments are required. Alu sheets have been ordered for a new version with separate power supply unit.
See terms – opens in a new window or tab. Add to watch list. Visit eBay’s page on international trade. Moving wires around at any stage during construction didn’t make any reduction in hum at all.
With uF cathode bypass capacitor and a operating into a nominal 10k load it should be around 6. Simply more hifi in the true sense of the word. The battery bias may be part of the good sound too eliminating the electrolytic cap across cathode resistor.

There are 6 items available. Learn more – opens in a new window 66n6p tab. Frequency sweep from battery bias set-up. Takes a serious dust-free environment. Have tried external, heavily regulated 6 V supply: The other channel still had unacceptable hum levels I use a 12″ Altec C right in my face on the workbench while working on the hum problem.
This reduced hum considerably and one channel was silent. Right out of the boxthese 6N6P tubes serves you another meal compared to My system wasn’t exactly lacking detail and transparency before, but in terms of transient quality and harmonic structure I get a subjectively more true presentation. Visit eBay’s page on international trade. I did have some trouble with the PSU having to swap ECC83 tubes to find one that would draw enough current to make a stable output voltage. No additional import 6np6 at delivery!
This amount is subject to change until you make payment. Have one to sell?
Removing the mains transformer calls for some serious redesign measures and 40 cm width may not be enough for placing mains and output transformers with enough distance. So, with the capacitor removed and a 1. Removing the choke also from the inside to the top behind the mains transformer helped somewhat further and if I ran my Audio Mirror amps at 1 volt sensitivity currently at mVI’d probably be where hum level is acceptable.

Even the TRAM2 features capacitor coupling and no matter how good caps we use, caps are crap and colour sound.
For the last year or so, I’ve been using Amperex tubes outperforming the valves – to my ears. What’s left is making front panels, led indicators and a relay switch that allows the preamp to be turned on from the main unit. Select a valid country. Some good advice on hum problems can be found here at: In the town where I live, Aarhus, we have a public workshop, Huset The Housewith a metal workshop, where I can bend the aluminium sheets.
