ECL86 opinions please
Ian Iveson
one pack? Are they common, and what are they good for? Any views
appreciated.

The ECL86, one of my preferred output tubes.
The Heathkit amplifier model AA-32 uses
3 x 6EU7's (preamp section) and four ECL86's as output tubes.
This particular model is one of the best small budget HiFi amplifier I've ever
heard.
even my son (15 years old) likes it and get one installed in his bedroom for
daily use.
If you have a chance to see one, try to get it home.
Use it with small but efficient speakers and you'll know what I mean.

(I'm collecting european radios and own the Philips model B8X44A + the
LoeweOpta
model L010K, both are stereo and each one uses 2 x ECL86's as output tubes.
These radios sound unbelievelable good, specialy in small areas like bedrooms)

More like half an ECC83, and a slightly less powerful version of an EL84.
The latest design of the triode/output pentode pair made by Mullard. They
were used by some recent (within last 15 years) commercial amps in UK, Audio
Innovations and Edison.
I have an old UK made Armstrong receiver using them in pushpull pentode mode
which sounds quite nice despite tiny output transformers (compared to my
Leak Stereo20, which uses EL84s in UL push pull, for about the same power
output).

satisfactory tube (not a great one), and I use one of these in a low power test
amp that I cobbled together to test tubes for microphonics.
Marshall made a small combo amp that uses a pair of ECL86's. The power
pentodes are connected in push-pull, and I think they used one of the triodes
as a gain stage, and one triode as a phase splitter. I don't care for the
sound of it, and it never really caught on.

(not an EF86), and is my favourite valve ! The pentode has a dissipation of
9W and is good for 4.1W in single-ended mode, but in P-P can muster over
10W, with the added advantage that you now have two small signal triodes
with which to build the previous stages.
I have an enormous quantity of ECL and PCL valves (same valve but different
filament voltage) and would be happy to send some at cost, with a view to
spreading the word as to just how good they are. You can see my professional
interest in them at www.diyaudio.com under Ko'lok.

halves seemed in the wrong order. I've seen EL84s as drivers, so this is
presumably fairly conventional? Both are common-cathode, with lots of local
nfb.
Thanks.

I do not have the Heathkit, but I love my dimunitive Rogers Cadet III and Knight.

Now I've thought about it, this may be a fortuitous discovery. What I am
building is a pair of simplified, clean running AC15s and a parallel bass
processor. The bass bit was to be another pair of EL84s overdriven into a
small OPT (don't ask!).
How would an ECL86 take to being driven by a EF86? I could use ECL86s
throughout, actually, except I've already got the ECC83s I need.
cheers, Ian

I took a look at the AC15 at www.voxshowroom.com and note it has 2 ECC83s,
and ECC81 and 2 EL84s. Could you email me a circuit ? There seems an awful
lot of preamplification here, and I really need to know what you intend, but
it sounds a wonderful amp with a real piece of history behind it ! On the
face of it, given that you have the ECC83s, I would have thought that the
triode sections of the ECL86s could jointly function as the ECC81.
Best wishes

I've been tidying the house. But I still can't find the original copy I had
of the AC15. I have a model of it, but I've ripped out most of the
tone-shaping (which, together with the overdrive potential and the effects,
accounts for all that gain).
Spare gain in mine is consumed by local NFB.
Then I put all the dirty stuff in its sidekick bass amp. This is the part
that I'm now having difficulty with. I haven't settled on OPTs yet so most
things are variable. Like it's been changed a hundred times already.
I'll send you my circuit, and I'll send you the AC15 when I find it. I've
found every other VOX, it seems.....
Anyone else got the AC15? Duncan.....?

the circuits but they were returned.

television-audio in one tube. It is specially designed to deal with
audio. It was also common in radios (as output). Not a bad tube, rather
the contrary. And common and cheap. Though note that the P/E/U (heater)
isn't really the only difference, there may be others btw - say - a
ECL86/PCL86/UCL86. /Pär
