John Findlay plays a Clark Belmont Reverb. This is our replica of the original, vintage 1963 – 1964 blackface Fender Vibrolux Reverb amplifier. The amp in the video footage is our stock model with a pair of Weber VST 10F150T speakers, (our favorite Jensen C10Q replicas), Jupiter Red Astron capacitors and Allen Bradley carbon comp resistors. The guitar used is an original, vintage 1960 Fender Stratocaster with Harmonic Design “Vintage Plus Strat” pickups. John starts off by playing with no added effects, slowly turning them on one by one show what the Beaufort Reverb is capable of both with and without pedals. His pedal chain consists of a Peterson strobe tuner, a Boss DD-3 Digital Delay, a pair of Love Pedal COT50 overdrive pedals and a Catalinbread Dirty Little Secret fuzz.

This is what was called an attache radio, for obvious reasons, due to the shape of its case. Opening the set activates the radio. The AM and LW antennae are located in the lid. Uses an AD14 Low Tension battery for the filaments and a B107 High Tension battery for the high voltage. The circuit is a standard four-tube battery type, and came to life once it was re-capped. In fact, just before I did this video, I had to replace one that I missed–the volume stayed the same no matter how the control was turned. There was a small .01 cap that had one of its leads broken. I wouldn’t have known it was a capacitor because it looked like a standard carbon resistor. Once replaced with a poly, proper operation was restored. This is my second Model N. The previous one was purchased from Hawaii, of all places, and was in worse cosmentic condition.
Excuse the messy playing. Here I compare my DIY germanium fuzz face (Transistors AC128 & 3AX31C), with Volume/Pre-gain/Fuzz controls to my DIY silicon fuzz face (Transistor 2N2369A) with volume/pre-gain/mids/fuzz. Both were made based on General Guitar Gadget PCB and enclosures. The only thing that differs is that the silicon is the complete kit from GGG and the germanium has parts that were ordered from smallbear (except the AC128). The germanium has higher gain trannies than the silicon, that’s why the fuzz controle is almost to the max for the silicon and at about 1 o’clock for the germanium. The germanium is PNP with metal film resistors (positive ground, powered by a current converter device based on a MAX1044) and the silicon is NPN with carbon comp resistors. I’m playing trough a Blues Junior III billM modified, master on 8 with my Fender Stratocaster w/o trebble bleed. The wah is a VOX V847 with Soul Sabbadius inductor, and Mallory caps .22 caps. True Bypass, led, etc.. The vibe is a danelectro cool cat vibe modified. If you have questions, I’ll be glad to answer.
As Henry Rogers told me, “You can never have enough CR-88A’s!”…..so I picked this CR-88A up from some super nice people in Quebec, Canada. It wasn’t cheap to get it to California but well worth the price for the careful packaging done by : Surplus 2D Ltee 813 St-Jacques St-Jean-sur-Richelieu Quebec, Canada J3B-2N2 Telephone # 1-450-346-7460 These folks went the extra measure to ensure this approx 100 lb (50 kg) receiver got here safely. With it and my other CR-88A (see Youtube videos), I will build a dual diversity receiving system. What is diversity? Well, get more info here at www.radioblvd.com The audio you hear is piped thru an amp from KCEA on a wireless internet radio to an HP 8640B signal generator. From there it goes at 30 MHz to an antenna and then is received by the CR-88A on a longwire antenna. These days it is the only way to get decent music onto your vintage receivers. There is little music on shortwave anymore. This CR-88A was in excellent shape to begin with. I did clean the tube pins and sockets, and all the contact surfaces on the rotary switches. Basically little else was touched. I do need to test and replace the old carbon resistors that have edged up or below their rated resistances. This is very typical. The capacitors, mostly oil type, are performing well, like the day they were made. Incredible performance for a piece of 1947 technology. Enjoy. Greg K6SRO
In life it’s important to be flexible. But what do you do if you want to measure how flexible an object is? You use a flex sensor. A flex sensor uses carbon on a strip of plastic to act like a variable resistor or potentiometer (CIRC-08) but instead of changing the resistance by turning a knob you change it by flexing (bending) the component. We use a “voltage divider” again (CIRC-08 & 09) to detect this change in resistance. The sensor bends in one direction and the more it bends the higher the resistance gets–it has a range from about 10K ohm to 35K ohm. In this circuit we will use the amount of bend of the flex sensor to control the position of a servo. wiki.netduino.com
