TJYarbro Joined: Mar 18, 2018 Posts: 10 SF Beast Bay	Posted on Mar 19 2018 09:12 AM Interesting. I got some raspyness at volume so I backed off the gain pot a little. The sound became ...'Crystaline'. Being used to the FRV pedal, through the SurfyBear, the sound of my instruments are MUCH clearer, and shows off the tone for which I built them. The attack is pronounced and right up front. When double picking, you almost can't tell there's any reverb at all. It's not at the back of the hall anymore. Is that a characteristic of the accusonic pan I'm using? Do y'all find different pans change that attack character? — https://www.facebook.com/gnarlymen/ https://gnarlymen.bandcamp.com/ Top

The most usual things causing this problem are: - MOSFETs not isolated from ground. - Bad soldering joints. - RCA cables. Have you checked these things? https://www.surfyindustries.com/images/faq3.png Last edited: Mar 22, 2018 16:26:44 Top
Aldersea Joined: Sep 10, 2017 Posts: 8	Posted on Mar 22 2018 05:54 PM RCA cables are ok, that I am sure of. When I turned the unit on the mosfets were definitely isolated from ground, I just removed the tape for re-soldering ease. I guess that just leaves the soldering job? I’m a beginner when it comes to soldering, but I’m kind of able to see when it’s bad. I’ve checked and re-liquified the solders several times already :/ Top

Mischa Joined: Aug 29, 2017 Posts: 35	Posted on Mar 28 2018 12:53 PM Very pleased with my latest build: a trem/verb combo. A befriended designer did the artwork. Extra features: dual mix setting, cap switch, wet/dry push-pull dwell pot for studio use and an order switch (trem into verb or vv). Thank you Surfy Industries for your fantastic designs and products, they rock! Top

Pablomago Joined: Mar 23, 2017 Posts: 85 Fort Collins, CO/Moonstone Beach, CA	Posted on Apr 01 2018 10:17 PM I have a dead '70's "Reverb/Echo" unit at home that would make a good case, and a couple of reverb tanks that may be right. I think it's time to do a build! — All opinions expressed by this poster are well thought out and based on actual experience and/or scientific experimentation, except for those which are knee-jerk reactions or good sounding fantasies.

otaznik Joined: Dec 27, 2013 Posts: 10	Posted on Apr 09 2018 11:43 AM Are there any specifications or personal experiences for heatsinks? I'd rather mount heatsinks rather than screw to chassis. Two get pretty hot in a matter of seconds, third is ok to touch. I have these simple TO220 heatsinks (should be 22 K/W). I'd rather overdo it in case it stays powered for hours on end but I don't know what to aim for. I don't want to have to replace them. Top

The original surfy bear had a pair like this: (thanks Ariel) I think they're between 14 and 17 K/Watt. Top
bjoish Joined: Jul 06, 2010 Posts: 596 Stockholm	Posted on Apr 09 2018 12:47 PM Yes, since the driver is a class A amplifier (just as the 6G15) the MOSFETs get quite hot. This is why I normally recommend using the chassis an efficient heatsink. The MOSFETs are specified for operation upto 175 deg.C, but I recommend a bigger pair of heatsinks than shown on your picture. Top
SurfHusker Joined: Feb 07, 2018 Posts: 10	Posted on Apr 09 2018 03:12 PM Hello! I've been lurking in this thread for a couple of months and am in the process of assembling a Surfy Bear unit of my own, which I'm going to install in a Harbor Freight tool box. I've been studying this thread and practicing soldering and I think I'm ready for the final assembly. However I have one question (and I hope it's not too dumb). I drilled the holes in the tool box last week and put all the switches and jacks and knobs in to make sure everything fit, but I noticed that when I put in the potentiometers for dwell, mixer, and tone they all have a tab on one side that makes them fit unevenly. What is the best way to install these? Should I just get more nuts to thread over the tabs? Top
