Radio has built-in Telescopic antenna datasheey short wave reception that extends to 26′ and is perfect. The original leather shoulder strap is also in great shape. Interfacing considerations[edit]Like DTL, TTL is a current-sinking logic since a current must be drawn from inputs to bring them to a logic 0 level. Those were checked prior to installation as well. Radio looks and works great.

TTL inputs are the emitters of bipolar transistors. Secondly the battery compartment door is missing.

CV – ST – PMIC – Voltage Regulators – Linear – Kynix Semiconductor

Momentary push button dial lamp switch. The radio looks good, and works perfectly. Utilizes 4 standard ‘D’ cell batteries. Typically, TTL chips integrate no more than a few hundred transistors each. Combination of 5 bands covered by 3.

This drawback is usually overcome by buffering the outputs with special line-driver devices where signals need to be sent through cables. For this reason, since more than 20 years many research efforts have been dedicated to on-chip embarked tiny reference field effect transistors REFET. It consists of the two n-p-n transistors V3 and V4, the ‘lifting’ diode V5 and the current-limiting resistor R3 see the figure on the right.


However, this may be an issue if the electrode has to remain immersed on-line for prolonged period of time, or is inaccessible for particular constrains related to the nature of the measurements itself geochemical measurements under elevated water pressure in harsh environments or under anoxic or reducing conditions easily disturbed by atmospheric oxygen ingress or pressure changes.

Help, where did my Varicom thread go??? November 26, Tolex, speaker grill, dial and everything in pristine shape! Archived from the original on Small chip in back lower casing. The CRT is still inside the tube housing and the wiring harness does extend into the lower case.

7915CV – Negative voltage regulators

7915cb Works uses 9volt battery. Radio is excellent condition with currently clean battery compartment and clips had previous minor corrosion to spring clips, but clean now. But a transistor count of Battery compartment had past minor corrosion, but has been cleaned.

C1 is required if regulator is located an appreciable distance from power supply filter. Journal of Solid State Electrochemistry. Minor wear to the speaker grill chrome plating.

It picks up great and sounds huge.

Functions within a single package generally range from a few logic gates to a microprocessor bit-slice. If the reference electrode used in contact with the solution is of the AgCl or HgCl2 classical type, it will suffer the same limitations as conventional pH electrodes junction potential, KCl leak, and glycerol leak in case of gel electrode. They are usually missing many parts and portions of wood veneer. Unknown model as internal label is missing.


Since it’s analog, and Proton quality, it just works! TTL became the foundation of computers and other digital electronics. With the exception of a some cracks around the back battery compartment and around the handle, the radio looks great! On all my they stay at v up to around volts input, then they go up with the input voltage.

PDF 7915CV Datasheet ( Hoja de datos )

Features larger body, external speaker jack, earphone jack and external antenna jack. Both front and back covers snap on perfectly. Very useful flip-up time chart with time zone conversion wheel.

Only minor wear to finish.

dwtasheet Measures 4′ tall and 4. The AC cord has been replaced with a new one. There has never any leakage in the battery compartment.


Some people get lucky, but many do not myself took a week of troublshooting to get my first GSSL working with just turbo mod. We did power it up with our bench 12 DC power supply.

We have given it a cleaning inside and out which included cleaning the volume pot volume control still noisy. No cracks in plastic datasheeh, just normal wear. When troubleshooting datashest malfunctions, often, most of the problems have to be searched for from the side of the reference electrode. Not much left of the insides, just the speaker.
