The ALFA AS301AN (PDIP-8) is a general purpose operational amplifier. This amplifier offers many features which make its application nearly foolproof: overload protection on the input and output, no latch-up when the common mode range is exceeded, and freedom from oscillations and compensation with a single 30 pF capacitor.

The ALFA AS3340-HYB is based on The ALFA AS3345F in QFF-24 package with addition of a PWM comparator. Such a solution greatly minimizes frequency modulation by PWM control circuit but allows PWM output be compatible with AS3340.

The ALFA AS3320 (QFN-24) is a high performance voltage-controlled four-pole filter modelled after the CEM3320, with on-chip voltage-controllable resonance. The chip can be configured as an lowpass, highpass, bandpass, or all pass filter. It has an exponential (V/Oct) frequency control input which can cover more than ten octaves with little control voltage feedthrough.

The ALFA AS3310D (SOIC-16) is a high performance voltage-controlled analog ADSR envelope generator that is pin-for-pin compatible with the CEM3310.

The ALFA AS3394E is a complete analog music synthesizer voice-on-a-chip intended for software control by a microprocessor system. PDIP-24.

The ALFA AS3364 (SOIC-16) is a quad general purpose voltage linearly controlled VCA intended for such applications as voltage controlled amplifiers, filters, and waveform generators. Each VCA independently provides linear control scaling over greater than a 100 dB range. Complete with virtual ground summing inputs, wide voltage compliance current outputs, and control inputs referenced to ground, The ALFA AS3364 requires exceptionally few external components and is extremely easy to use.

The ALFA AS3363 (SOIC-16) contains three VCA blocks, which are intended for use in musical synthesizer applications (VCA blocks, voltage polarizer, multiplexers, morphing, ring modulators etc.).

The ALFA AS2164 (SOIC-16) contains four independent voltage controlled amplifiers (VCAs) in a single package. High performance (100 dB dynamic range, 0.02% THD) is provided at a very low cost-per-VCA, resulting in excellent value for cost sensitive gain control applications.

The ALFA AS3350 (SOIC-16). is a dual voltage controlled state-variable filter intended for electronic musical instruments and other signal processing applications.

The ALFA AS3052 consists of 8 NPN transistors, 2 diodes and 1 buried zener on a common monolithic substrate. Transistor array allows variety of connections: differential pairs, different type of current sources, different kind of multipliers/dividers, etc. SOIC-24.

The ALFA AS3280AD (SOIC-16) consists of two variable operational amplifiers that are designed to substantially reduce the initial input offset voltage and the offset voltage variation with respect to changes in programming current. This design results in reduced AGC thump, an objectionable characteristic of many AGC systems. Low Offset Voltage Drift: 5uV/'C (Max), Low Initial Input Offset Voltage: 500µV (Max).

The ALFA AS3280 (PDIP-16) consists of two variable operational amplifiers that are designed to substantially reduce the initial input offset voltage and the offset voltage variation with respect to changes in programming current. This design results in reduced AGC thump, an objectionable characteristic of many AGC systems.

The ALFA AS194DE (SOIC-8) is a junction matched monolithic NPN transistor pair with an order of magnitude improvement in matching over conventional transistor pair.

The ALFA AS3046 (SOIC-14) consists of five general purpose silicon NPN transistors on a common monolithic substrate. Two of the transistors are internally connected to form a differentially-connected pair.

The ALFA AS394DE (SOIC-8) is a junction matched monolithic NPN transistor pair with an order of magnitude improvement in matching over conventional transistor pair.

Platinum matched tubes. The Tung-Sol KT170 also has been designed to amplify low frequency power in the output stages of High-End Hifi audio amplifiers. It has a specially engineered glass bulb that maintains the highest vacuum levels and at the same time helps heat dissipation when operated at high power levels.

Matched & balanced tubes. In 1959 Tung-Sol developed a premium, up-rated version of the 6BQ5/EL84 for use in industrial and military circuits. This tube was designated 7189. Due to its higher plate voltage rating and increased clean headroom, it became a favorite power tube for use in medium power stereo amplifiers and receivers. It was also used in high-end guitar amplifiers manufactured by Magnatone. Due to its increased ratings, it was considered as an upgrade for 6BQ5/EL84 amplifiers for increased performance and reliability.

Matched and balanced, low noise, low microphonic, version of the 12AX7 that meets all specifications required for the tube to be designated 7025. The original 7025 tube was a 12AX7 that was tested and selected for the lowest noise and microphonics for use in the critical first preamp stages of amplifiers where noise and microphonics could be an issue.

6CX8 NOS, made in USA.

This is a redesign, styled after the early British MOV KT88 tubes. It has the same large heavy glass envelope and a polished metal base. Excellent tone and great appearance. A preferred choice for high-end audio and powerful bass amps.
