Default does anyone know this amp?

Hi,

I found this amp at an auction. The seller doesn't know the model nor the brand name. Does anyone know it? Is it worth the 150 euros they are asking for?

thanks,


JP

Looks like a homebrew type to me...

Yes its prolly worth that if it goes and has the tubes... It could be good source for parts and chassis etc; those o/p transformers aren't cheap. It could be a nice project to restore, thats what ive been doing and its very rewarding.

Love that rugged grille

JP,
I don't know why but the design looks like 50s English. You might post some more pics with the cage off and let us know the tube brands. The type of electrical plug might be a hint as well.

Thank you very much for your answers.

The tubes are Mullard (old logo, the seller says) ECL86, and delivers 15W (again as the seller claims).

ECL86 is a triode+an output pentode. Think 1/2 a 12ax7 + not quite an EL84/6BQ5. Good for about 3.5-4 W in SE and 8-10 in PP. The ECL86 is similar to the 6BM8/ECL82 in the WAVE 8, that gets many accolades.

What is the tube on the front of the board?

Quite a bank of old germainium rectifiers. It is not a home built with those boards. Both the Germans & the English used those flat-blade bolts holding down the boards. From the way the green & yellow filament wires are routed & the Mullards i'd guess British.

Sizable OPTs are probably an indicator of a higher end amp. The screw connectors may indicate a pro amp out of a theater or some such.

In good working order it is probably worth the asking (and maybe then some).

With little or no circuit mods the 6BM8 could even be used -- it is current production, i don't know if anyone is making ECL86s.

British or German amplifier. As per the boards layout reverse engineering may be very easy, but you need to have certain knowledge of valve electrronics to draw schematics. Selenium rectifier can be easily replaced by the well know 1n4007 silicon diodes. ECL86 or ECL82 expected to deliver fantasic european sound. I would go with this amp and put it again to run. Of course I am basing assumptions the Output and power transwformers are OK.

can you see if the power transformer is 230v or 110v.

i ask this as the plug does not look like a UK one...........it may just be it was in a bigger cab to start with, but hav'ing said that it looks to good to go in a bigger box?
