| Ever tried putting a cap inline with RCA for XOVER I second the Harrison Labs FMOD passive x-overs from Parts Express. I've used them successfully in the past to bi-amnp my party system.http://www.parts-express.com/wizards/searchResults.cfm?searchFilter=fmod%20crossover. | |
| Upgrade from Classe CA-151 for AAD 2001s Speaking as a longtime Classe owner, replacing that CP-35 alone should improve things signicantly. A CP-50 or CP-60 should keep you happy and rediscovering your music collection for some time. | |
| Binding post upgrade for Classe CAP-151? If you are familiar with the CA-300 and CA-400, you will know that the way the amp is constructed, there is no room for bypass caps. The CA-300 has thirty-six 4,700uf filter caps, stacked in two tiers of 18. IMO, one of the DR models with their mo... | |
| SANSUI AU-719 Gets Really Hot? What you describe does not sound normal. The amp should not be running that hot. Have a technician check the bias, which may have drifted over the years. The amp is more than 30 years old and should be looked at anyway. | |
| Binding post upgrade for Classe CAP-151? The two red Wima caps you're talking about are the two 0.1uf op-amp decoupling caps, C105 and C106. The 100uf caps must be the two +VCC and -VCC decoupling caps. No modification to the CA-300 chassis was necessary to fit the WBT 0702 posts. Howeve... | |
| AC condition TV picture breakup or sudden shrinkage when an AC compressor kicks in is a symptom of sudden severe voltage drop. It is not RFI related. Hevac1's suggestion is good, although I think some assumptions are being made in this thread. What size is the... | |
| Binding post upgrade for Classe CAP-151? Q1rene, yes, I could hear differences. The CA-300 has no input caps to replace. Trying different input buffer op-amps may or may not be worthwhile. | |
| Power On First/Off Last Device? Loomisjohnson, in addition to the old Adcom line conditioners, the Belkin PureAv PF-60 power console has eight outlet banks, each with programmable turn-on delays of 5, 10 or 15 seconds. You could set the outlet bank the amp is plugged into so tha... | |
| NAD 3155 Pops when turned off Turn off pop could be the result of some excessive DC offset appearing at the output(s). The DC could be high enough to cause nuisance pops but not great enough to trigger the protection circuitry. This can occur in older amps as parts age and val... | |
| Surge Suppression vrs. Lighting and Power Spikes I only read the first two paragraphs of the OP. When there is lightning or threat of it, I always unplug my system. the small gap in a power switch or breaker will not stop lightning. No kind of surge protection is a match for a direct lightning s... | |
| Classe Delta CA-5300 The Home Theater magazine review from which you made your "discovery" only said that the CT-5300 went into protection mode at 190 watts into 4 ohms. It did not say whether that was with all channels driven. This is probably deliberate current limi... | |
| How Much DC is OK on a Power Line? Pcoombs, harmonic distortion and DC are two different phenomenon. A UPS or power regenerator like one of the PS Audio units should cure harmonic distortion issues.Peter_s, I said in my post above that as little as couple hundred millivolts of DC c... | |
| How Much DC is OK on a Power Line? Peter, what model Classe amp do you have ? A lot of later production CA-XX0 series amps have DC blocking circuitry, and for earlier production models that did not have it, the DC blocker circuit board was available as a retrofit. A couple hundred ... | |
| DUPLEX RECEPTACLES YOUR EXPERIENCE Jejaudio, why not also use the R-1 in your DIY power strip ? I'm sure the Porter Ports are fine sounding receptacles, but are they really "all copper" ? Pure copper is too soft to be used for recepetacle contacts. That is why the Oyaide R-1 uses b... | |
| Best pre-amp w/phono for $1000-$1200 USED/MINT PS Sunnyjim, there is a CP-50 listed for sale here on A'gon right now that is within your budget range. |
