Adapter sockets can be made to use 6BQ5's if you dont like the sound of the 6V6"s. I can't seem to find anything else LOL!!! Unlike power transistors, valves do not have to be mounted on heat-sinks. Messages: 53, PakProtectorSep 8, If they do not, then recheck everything on the board and all the wiring because there is undoubtedly a mistake in it somewhere. If the loudspeaker connections are reversed the amplifier will be heard to oscillate. Some output transformers have special screen grid tap-off points on the primary side. Those in the know now say, as, indeed, they always have, that valves sound better than transistors.
The Dual Quad 84 Tube Integrated amplifier (PPP EL84) Photo UK Audio Mart
Am thinking about building something like this, perhaps triode strapped, should get approx 11 watts in class A. Anyone seen a schematic of that. I am running music through my PPP EL84 amp as I write this. http://webpages. This time I hid all the. Can anyone tell me of a higher powered EL84 based amp??.

the Peavey " Classic 50/50" is a commercial stereo PPP EL84 amp that's kind of.
Or upgrade your speakers and you possibly will not run out of power anymore with what you already have! Great synergy!!!
If I don't find anything tube wise that is affordable, the the Virtue will be a shoe in!!! Lines from the input socket to the board must be made with screened cable.
Plenty of room has been left on the board for mounting smoothing capacitors C11 and C Valve amplifiers are 'in'.
That ic was mounted on the chassis with a proper insulator. So, for higher powered applications, I am not. Hi all, I'm after a schematic for a power supply with a bridge rectifier and without a choke for a 4 x EL84 PPP power amp and a 2 x 12AX7.
Some audiophiles, as we have already mentioned, prefer tubes but amateur radio users have also refused to let the 'new-fangled' transistor supersede their beloved valves.
I appreciate all the suggestions!!! If you want a stereo valve amplifier remember that all the components must be duplicated.
Note that the values of C2 and R4 depend on the impedance of the loudspeaker used. In this case we have used a supply transformer intended for use with valves. If they do not, then recheck everything on the board and all the wiring because there is undoubtedly a mistake in it somewhere.
A word fitly spoken in proverbs
|TetrodeSep 8, The fact that we have designed a valve amplifier does not necessarily mean that this is our opinion.
The power stage consists of a conventional push-pull circuit with two EL84s set to an anode voltage of V. Log in or Sign up. No, create an account now. In spite of its compactness everything fits on the board, except for the two transformers and R21 which is soldered across the loudspeaker terminals.

In general, construction is just the same as for any other Elektor project but there are a few points to note. Finally, keep all the wiring as short as possible so as to minimise loss. It is time for the 'acid test'.
Hmmmm wonder how often those show up??

Make sure the cable used for this is capable of handling the heater current of 2 A.

|Any "single pair of EL84" push pull amps will net you 20wpc at the most, wanting more power you'll need to do like the Stingray, run parallel output tubes, you could build one.
We have also been bitten by the valve bug, as witnessed by this amplifier. I can't seem to find anything else LOL!!! Discussion in ' Tube Audio ' started by sideways2Sep 8, When fitting the components to the printed circuit board simply follow the sequence normally used. Appreciation of sounds is, in any case, purely a personal matter so everybody simply has to decide what he personally prefers.
It is important to have enough ventilation slots in the case as the valves dissipate a lot of heat and this must be dispersed.
