And...all seriousness aside...(or not)...I have purchased three sets of Lorenz SEL PCC88 tubes from this vendor on e-bay:

 

http://www.ebay.com/itm/390528285455?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

 

The mail is a little slow from Vilnius Lithuania, but the tubes are great!  Frau-Olia (Olga) has more up for sale.  They come without boxes but are well wrapped in bubble-wrap and in a sturdy box.  I've had no problems with the shipping other than the first set was delayed (probably due to the holidays).  ...And they look brand new.

 

Cheers!beerchug.gif

All new components are on the way.

 

606 Project Scope

 
Replicate circuitry of 606 using new components.  Resistors, Capacitors, Pots, switches, lamps.
Provide all original testing functionality: Shorts, Quality, Grid Emission. 
Eliminate all valve sockets except 9 pin.
Instal 3 discrete 9 pin sockets to accommodate  ECC88, 6BN8 and 12AX7 valves.
Provide circuitry to accommodate the 9 pin valve types from a singleTypical  transformer secondary.
 
Philips ECC88
Heater: 6.3V 365 mA
Typical Plate: 90V  15 mA  (per document.  I suspect 1.5 mA)
 
Sylvania 6BN8
Heater 6.3V 600 mA
Typical Plate: 100V 1.5 mA
 
GE 12AX7
Heater: 6.3V  300 mA (In Paralel)
Typical Plate:  250V 1.2 mA
 
Transformers.
Plate Transformer:  Hammond mfg.  Model 166F120  Secondary  120VAC C.T.  0.3 A
Heater Transformer:  Hammond mfg. Model 166G6  Secondary  6.3VAC C.T.  0.6 A
 
Challenge:  Engineering 250V plate voltage from a 120VAC trans.  If I can't do this I will abandon the 12AX7.
Challenge: Calibrating the Dixson model 430 meter.  Process, known good tubes and B&K 25 M Ohm calibration procedure.
 
Fabricate new enclosure and panel.  Provide testing taps for multimeter and oscilloscope.

I ordered mine on 19 Jan and just got them yesterday (although my first order took three and a half weeks).  It shouldn't be too much longer for you.

The mail is a little slow from Vilnius Lithuania---This is where Sean Connery was born (CAPTAIN RAMEOUS) in the movie Hunt For Red October--Maybe I should contact him and see if he could pick them up for me!!!

So, would that be a "sub-surface" postal rate? tongue.gif

Don't know if it would be cheaper--But it sure would be quicker!!!!

 

Put it in a Torpedo and aim it for the nearest US POST OFFICE.....

Haha I was messing with ya man being a analog component much like some capacitors that I have seen a change in over time pretty much proven.. I would agree some amount of time on the Audiophile front is prudent.. Now for Preamp tubes same situation we have with the Lyr different tubes really make a difference in some Guitar amp designs I have one amp that is very complex it allows you to switch from A to A/B to Pentatode etc etc it does it on the fly mechanically not electronically now it works great when it works haha but its in the shop more than out.. smily_headphones1.gif

Yeah I think I will 69 hours that sounds like a good one.. smily_headphones1.gif

hey guys, i know this is going to be a little off-topic, but im struggling to pull out my tube amps. Is there a way where i can achieve this without being too scared of breaking pins or damaging the units themselves?

Use rubber gloves (I dont like the oil from skin on the glass of the tubes, just like on light bulbs I believe it will shorten the lifespan, it also helps with grip) and move the tube side to side back and forward whilst all the time gently pulling upwards. Not too much on the moving side to side etc...

Get a tube glove. They work fantastic, the smaller end fits a 6DJ8 sized tube perfectly.
