One perfectly matched quad of genuine EL34 / 6CA7 made by Mullard, Blackburn in 1975, Xf3 codes. 


They are rebranded Siemens (Siemens has never made any EL34!), NOS NIB, in original Siemens boxes. 
Top mica spacer with 10 support points, folded plates (stapled), two slots on plates, black base with central hole in guiding pin. 


I had a few dozen of these tubes (all the same date codes!!!), and all quads I have are carefully tested and matched by plate current on my Metrix U61-B tester. Due to big number of tested tubes, they are matched within 5% or less!!! These are very strong examples, selected from big number of the same batch tubes!

It's really hard to find four practically exact genuine NOS Mullard EL34 with perfect prints and the same etched codes today, be fast and take this opportunity while they are still in stock!!!












This is a private listing and I do not give a warranty about the quality of the valves, and I do not accept returns. These valves are carefully matched and they are 100% in perfect working condition, I simply can not take responsibility for some users who do not know how to change tubes in their amplifiers.

A natural storyteller
Format: Paperback
Three middle-aged women hike the mighty John Muir Trail, the crown jewel of California that covers over 200 miles of steep and rocky terrain in the Sierra. It was a big deal. The 3-week wilderness trip extended over multiple, high-elevation passes, crossed roaring water and rose to the summit of Mount Whitney, the tallest mountain in the contiguous US at 14, 505 feet. Griffin’s storytelling comes naturally and with ease. This inspirational, follow-your-dreams story is easy to feel surrounded by because of Griffin’s vivid writing. Luscious accounts of landscapes, macro details of the natural world and the knee-knocking, quad-stabbing terrain puts you, the reader, right there. Conversely, the detailed prose is a huge liability in the pacing of this book. Mundane details are redundant as the book slogs on. Long descriptions overtake the read and the focus stays superficial. I would have liked much more character development, and better cadence and dialogue.

My Favorite Camino Read To Date
Format: Kindle
I have read dozens of Camino retellings. This, by Brad Chermside, is my most enjoyed. Brad is an excellent writer with no fear of exposing his insecurities and weaknesses, physical or social. His many metaphors are original and laugh-out-loud funny. He used several interesting writing techniques to keep me in suspense. The most effective being, from the start of the narrative, finding out if when he met the never met mystery woman, who was the catalyst for him beginning his journey, and he would click. It was eventually answered. Highly recommend the book. Hat's off to Mr Chermside on an excellent read.

Camino memories relived
Format: Paperback
I returned from my first Camino trip and I was wanting to stay in touch with everything related to the Camino - the friends I made there, movies on YouTube, and podcasts. It was from the podcast that I learned about Brad. He has been a constant companion to me, as I went through my own Camino 'withdrawl.' Luckily for me, after a couple of weeks from been back from the Camino, I am already able to schedule my next one. Brad's book brought back all the memories, and he put into great narrative and humor all the amazing and magical things that happen during the Camino, including also the challenges, the crying and the laughing. I am very grateful for this book.

Greatly enjoyed this book.

His long journey of self discovery is well told, with sprinkles of humor throughout. It made me long to take a pilgrimage of my my own.
