Something a bit different - old (E-super E-stereo) valve amp.   Smile




















Mullard EL34´s still going strong - but had to change the ECC83´s - along with the usual tweeks. Sounds great.  Big smile

No, not mine, just giving it a service for a friend. I think that he wants to put it in his studio.  Smile

It must be around 30 years old and the EL34´s are usually good for 30W-40W. Made in Barcelona, or Valencia, not too sure.

Aye, could be older. It´s all packaged up and awaiting collection, so not too sure about opening it up to check. I´m quite busy as well, so let´s see how the day goes.    Smile
