Tech Talk - Masco MA-17N PA System (1950)

PA amps are the hidden gold of amplifiers. Old Marshall PA amps as well as Hiwatt PA amps are the steal of the century. Here we have a Masco PA and we know how I feel about Masco!

Masco Amplifiers were largely a mail order brand available through Layfayette, Archer and other large electronics supply catalogs. It could also be purchased at music stores and appliance stores as an inexpensive house brand.

Masco PA heads are widely available and good quality. They were disgned for voice or music amplification. They differ from Guitar amplifiers in that they did not have the high gain preamp stages and produced more realistic tones. This makes them excellent harp amps.

Many harp players use masco heads with custom speaker cabinets or make a combination amp cabinet. They amps often have multiple speaker outputs to accomodate a variety of speaker combinations. The microphone input is perfect for a high impedance mic such as the JT-30.

MASCO stands for Mark Alan Sampson Company and the amps were produced on Long Island, NY during the 1940s and 1950s. The circuits in Masco amps were often incuded in SAMS photofacts and appear regularly on eBay.

Tech Talk - Masco MU-5

Older tube amps made in the 40's and 50's make terrific blues guitar and harmonica amps. This is a great review of the kind of sound you can expect from a Masco MU-5.
