The two types are similar in characteristics but not directly interchangeable.

These tests were done with a regulated valve power supply, a Tue model The language is mostly Dutch, but that shouldn’t be a problem. Grant Wills wrote to tjbe in early ; ” My new amplifier, based on M transformers sourced from Altonics, works a treat!

These days people tend not to use filter chokes in power supplies as there are plenty of high capacity electrolytics available at reasonable prices. At first it seemed to be a lost cause, trying to use this valve as an audio amplifier. Furthermore, this is my first experiment with enhanced triode mode. This too is better than the original quad of EL’s which managed watts ttube at best! As with all electronic experimentation, there are components hanging out everywhere.

The conventional pentode connection was the worst!

THE CONVERSION OF EL503 TUBE AMPLIFIERS TO USE THE EL36/6CM5/EL360 FAMILY OF TUBES

Most companies that used the EL output tube the Belgian company Faylon and the German Dynacord being just two examples most probably chose this tube for its short, stubby, fairly beefy, relatively low voltage specifications enabling a smaller overall height of their amplifiers? Ratings for use in Class B push-pull are readily available from Philips datasheets available on the internet.

So, that’s why I set the P d line to 15 Watts on this sheet. The second characteristic that I found problematic was that when using a fixed bias supply the grid voltage was critical within a few Volts, from trying to set an anode current of 50mA to being completely cut-off.

They are still holding in there with no change in any way. Secondly, if the component or valve tolerances are so far out that there’s not enough adjustment in the kOhm preset, the kOhm resistor can be reduced if the current can’t be reduced, or increased if the 6CM5 can’t draw the requisite 45mA. For single-ended application, the EL36 linearity is problematic to say the least, and available output power is somewhat less than a 6BM8.

Be aware of the fact, that the power transformer is wired rather oddly tubbe these amp’s. It is equally adaptable for the EL John contacted me in August – it quickly became evident that he had a much much greater knowledge of this interesting valve than I, and therefore I am most appreciative of his willingness to allow me to ttube his advice to me here.

Driving via the control grid g1 is not the way to use this valve for Class A audio, as much as I wl36 tried.

These are designed to work with no DC component in the windings and are ideal for these applications. The 6CM5 is not a plug in equivalent, although it might have the same or similar connections.

More valves in parallel will give more output power, but you will need to take out shares in the local electricity supply utility. As I build a lot of valve projects requiring an audio stage the 6CM5 has been of interest, especially as I have a huge quantity of them! You can only get about half the output power that tybe can get from screen grid g2 drive.

Outside Australia the 6CM5 valve is virtually unknown.

More gain could be obtained by bypassing the 6AV6 cathode resistor. I do not think that the full stories surrounding both this valve and the 6DQ6A, have come to light. They don’t look bad at all!

If however you wish to build a single-ended guitar amplifier, they will work up to 10 Watts quite well for lead and rhythm use. They normally rate in as a 12 watt plate wattage, but there is a lot of talk out there that they can and in fact do handle considerably more. I probably won’t bother including it in future amplifiers.

I have found other characteristics as well that do not lend the valve to audio applications normally. There must be at least 6BL8’s in my valve collection, and what a useful valve that is, for example.

Tuhe found that by winding a few turns on a toroid core an RFC radio frequency choke can be made and placed in series with the screen, close to the socket pin. Several el366 later, John emailed me further, to announce that some significant headway had been made in this regard. Really nice reverb, 2 x 12 speakers, uses two EL36 output valves, about 40Wcombo style, but not open back – the speakers are fully enclosed. These had all cost me a fair bit of eo36 and I still needed more!

Most CD players and modern hi-fi music sources these days have op-amp output stages which are low impedance and can also drive the transformer in unbalanced mode. This was starting to look good!
