OC83 PNP Germanium transistor from Mullard, OC83 PNP Germanium transistor in a classic SO-2 case (aluminium cover over standard Mullard glass test tube) My Pigdog Driver has the YJ OC44's and its better than any other Treble Boost style pedal Ive had but not by a mile. The first Beano I ever owned ( of 3 of them ) with a white dot NKT275 had the most quirky greasy mojo and I love a TB to have character and not be smooth and transparent.. but I also like to have a variable tone knob feature so I can dial in fuzz pedals low end that I stack into it.

The major pedal builders who have used them have declared their value-- sounding like a perfect Black Glass OC44: "The can type package is known to be much more consistent than the black glass package which I assume is why Mullard made their mil-specs this way.

The EL34 was the 1952 successor to the very successful EL37 and both share a high value of mutual conductance 11.0 mA/V. The OC44 and OC45 used in early transistor sets tend to be reliable. There are enough spares from scrap sets etc. to provide replacements for the occasional faulty device. Germanium diodes tend to deteriorate rather than completely die; often showing increased reverse leakage and increased forward resistance.

Interestingly, I have a few old volumes of the Mullard Technical Handbook (essentially a designers' guide to using valves). Volume 1 covers the normal run of the mill line of valves, and the data sheet for the EL84 does has 'characteristics' that differ from the PL84 and the UL84 (most likely because they are quoted at different anode voltages. mullard oc: mullardoc: mullard oc141: mullardoc141: mullard oc44 DatasheetWe can Supply Pricing and Datasheets for this part number: mullardoc44DatasheetWe can Supply Pricing and Datasheets for this part number: mullard oc72: mullardoc72: mullard oc72 DatasheetWe can Supply Pricing and Datasheets for this part number The early Philips/Mullard AF114 to AF117 signal transistor range worked well to 30MHz and far exceeded the performance of the original black painted glass body OC44 and OC45’s of early transistor radio fame as they had a much lower collector to base feedback capacitance and did Details about 2x Original Mullard PNP Germanium Transistor oc76, NOS-show original title.

I show three examples, one in classic GEC low-power encapsulation, one in a Mullard SO-2 glass can, and a third in a short SO-2 or TO-1 metal can probably made by Texas Instruments (UK).

The alloy-junction OC44/45 types were used in early AM radios, but were quickly replaced by the infamous AF117. When working, the AF117 does give much better results - the OC44/45 types had a higher base-collector capacitance which required neutralisation (essentially, a form of positive feedback)... mullard oc: mullardoc: mullard oc141: mullardoc141: mullard oc44 DatasheetWe can Supply Pricing and Datasheets for this part number: mullardoc44DatasheetWe can Supply Pricing and Datasheets for this part number: mullard oc72: mullardoc72: mullard oc72 DatasheetWe can Supply Pricing and Datasheets for this part number In January 1957 Valvo released the OC44, their first transistor suitable as an oscillator/mixer at broadcast band frequencies. This was matched again by Telefunken with their OC613. [Herzog 2001] Mullard Mullard was founded in 1920 by Stanley Mullard and began making receiving and transmitting tubes.
