That means the OC44 transistor has a negatively charged layer between two positively charged layers. Mullard used a different convention to identify the pinout and often printed a dot on the side of the transistor. BJT: Jul 29, 2019 · The earliest Silicon Fuzz Faces were quite distinct from the original NKT275 Germanium variety - being more strident and aggressive - and utilising BC108C and BC109C transistors, the third variety to be utilised was the BC183L which sounded a lot more like the warmer Germanium. Keywords - OC44 transistor datasheet. Keywords - OC75 transistor datasheet. Jul 20, 2008 · The AC128 sounds different but good in its own right. However, since this book was written in 1963 I can't find any of the parts online. Vintage Mullard Transistors This chart shows the pinout and data for AF114, AF115, AF116, AF117, OC26, OC44, OC45, OC65, OC66, OC70, OC71, OC72, 2-OC72, OC170, and OC171 transistors. The original Dallas Rangemaster unit shipped with either an OC44 or OC71 black glass germanium transistor. The low gain of the transistor implies a low base impedance, wich comes in // with the bias bridge, so the real input impedance of a RM is ver very low (around 12 Kohms) and cuts out all the higs just like a 50 ft long crappy cable. OC44 cross reference OC44 equivalent finder Feb 21, 2011 · Not only the transistor by itself actually, but also the low impedance of a germanium treble booster. The OC44 transistor symbol shows an arrow from the emitter into the base. The 139 is NPN and the 140 is PNP. I highly recommend the Geofex article on the rangemaster. The purpose of the Cross Refererce Guide is to assist you in searching for a part on our linecard by the manufacturer which is similar in function to products of other companies. Parameters and Characteristics. Could anyone tell me the modern equivalents to: OC44 Transistor (PNP) OC45 Transistor (PNP) OC71 Transistor (PNP) The first germanium transistors that I encountered as a kid were the glass-encapsulated OCxx types - OC44, OC45, OC71, OC81D, OC81, etc. There are enough spares from scrap sets etc. OC44 Transistor Datasheet pdf, OC44 Equivalent.

May 9, 2008 · Hello, in many repairs and DIY builds we find the need to know an Equivalent transistor to replace a failed one or for a new build. I like NPN rangemasters since they ease the powering scheme Jun 21, 2013 · I would need modern equivalents to these peices, especially the i. 01 A Max. Jun 21, 2013 · I would need modern equivalents to these peices, especially the i. Mullard also was supplying the SO-2 Glass Can style for Military use, calling it the CV7003, which were really the OC44 but tested to much higher spec, in the SAME glass can as OC44. Could anyone tell me the modern equivalents to: OC44 Transistor (PNP) OC45 Transistor (PNP) OC71 Transistor (PNP) Both transistors were made by the major transistor manufacturers in the early 1960's like Philips, Mullard & Valvo. OC75 cross reference OC75 equivalent finder OC75 lookup OC75 substitution OC75 replacement LIST Last Update. Keep in mind that germanium transistors vary a good deal. The secret to making these pedals sound good is biasing the transistor. There is an ongoing market for the OC44 on eBay because it was used in some early guitar effects units, in particular the Dallas Rangemaster , and purists insist that only OC44 PNP Transistor. transformers (made by technical suppliers ltd. The OC44 is a bipolar junction transistor (BJT) with an PNP-type configuration. f. , if that helps) and silicon equivalents to the germanium transistors. This is what makes the Swart Atomic Boost with its integral, gain matched, vintage NOS OC44 so important; it brings the boost WITH tone and soul. These were not an option that a customer could pick. Back in the day people had books with charts for transistor equivalents. The latter types listed were often further encapulated in an aluminium can for improved heat dissipation - the OC81D was often used as a driver (ahead of an inter-stage phase-splitting transformer), and a pair The OC44 and OC45 used in early transistor sets tend to be reliable. Could anyone tell me the modern equivalents to: OC44 Transistor (PNP) OC45 Transistor (PNP) OC71 Transistor (PNP) Two OC72 Transistor which are a 'matched pair BD139 or BD140 They are power Si transistors, and sound quite good actually. BJT: GA1A4M | The first radio frequency transistors produced by the Philips Group, and amongst the first in the world, were the OC45 and the OC44 both announced by Philips in October 1956.
