Heed canamp Mods Thread!! - Page 4

post #46 of 75
may i know what's the max measurement for the tank caps? Can i fit in 50mm caps?

50mm certainly not. I think it is 25mm.

nono i mean the height, i remember PinkFloyd uses 25mm x 45mm caps. Can fit in 50mm ones?

For you modders, I've posted my impressions from Sydney meet on modded vs stock CanAmp on page 64 of main Heed CanAmp thread.

i fitted 35mm caps in there and they barely squeeze in

63v 100nF film caps replaced with 250v 470nF Evox Rifa polypropylene caps

100v 100nF film caps replaced with 250v 470nF Evox Rifa polypropylene caps

IN4002 diodes replaced with UF4002 ultra fast recovery diodes

5W 100ohm resistors replaced with 10W 100ohm Sprague Koolohm resistors

63v 470nF film caps replaced with 250v 470nF Evox Rifa polypropylene caps

NE5532 OpAmp replaced with DIP-8 socket and fitted with DY2000 OpAmp

wanna ask, what type of opamp can i use on the CanAmp? Do i need to adjust the gain setting or other settings to accommodate different opamps? Currently i have some 4562s on hand but i'm not sure whether i can just solder a DIP8 adapter and pop in the 4562. Is there any "important" notes that i need to know before i pop in any opamps? Thanks in advance.

you need the datasheet.

First check if it's unity gain stable or internally compensated. Next check the bandwidth. If it's a high speed opamp, you'll probably need to compensate it by using caps. Otherwise it will oscillate and become unstable.

the stock Canamp OpAmp is the NE5532/

well, i just popped in a DIP-8 socket and when i tried the LM4562 is worked fine

make sure first and foremost that it is a dual opamp, otherwise you'll need two singles on a browndog adaptor

i had AD823s, OPA2111, OPA2107, OPA2604, NE5532 and LM4562 and they all worked fine if that's any help

thanks for the replies guys, so i don't need to bother about the gain settings or risk of making the opamp unstable? I remember someone did mention before that the CanAmp is gain 11.

I am going to do following when it arrives!

  • RUBYCON ZA capacitors for 100Uf and 10UF electorlytics
  • UF4002 Ultra fast diodes bypassed with 0.001Uf Ceramics
  • OPAMP rolling with LM4562
  • PANASONIC TS-HA 10000Uf 35V Capacitors
  • 100nF and 10nF caps replaced with polyprophelenes
  • 470NF Wima MKS4 Bypassed with Polyprophelenes
  • Caddock 100ohm resistors heatsinked
  • Silver wires and silver solder

Anyone have a source in the US for these parts?

Most of them I bought from Farnell UK. I think they do have US branch too! Newark?
post #59 of 75
looks promising

i think you should socket the opamp so you can roll others in

i personally prefer the analog devices sound with my canamp

LM4562 sounded a bit dead

Thanks d-cee for tips specially regarding the OPAMP pads in front of the amp. Yes I am going to socket it and have some Analogs OPAMPS too in my pocket. I will first try LM4562 then AD8620, AD8397 and so on to find the best sound. LM4562 in my XIN SMIV is pretty impressive!
I might sell it after modding as i have developed new craving for Gilmore lite if its SQ is on par or above Canamp! We all headfiers are crazy! But can't help the feeling!
